Chi Square Test Paper

all treatments contain the same type of soil, are planted in the same size of pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. ON THE TEST there will be a number of related questions about this section not just the question shown below.

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

Throughout this experiment, we are researching the effect on the growth and survival of Wisconsin Fast Plants using fertilizer pellets to help with the growth of the plants. Wisconsin Fast Plants is a plant member of the crucifer family which is related to other plants (vegetables) such as cabbage, broccoli, turnips, etc. This plants are small and can grow very easily because they go through their cell cycle around 40 days. Wisconsin Fast Plants Fertilizers are different materials used that can provide plants with the nutrients it need to grow. (1) These plants are a good model system to study because they grew very quickly and didn’t need a lot of resources to grow making them the perfect plant to use for studies. (4) By using the fertilizers,

A chi-square test was performed to determine whether there is a preferred attraction among men to women of their own race. When responding to the question, “would you swipe right on this profile,” (M=_, SD=_) there was a significant preference for the same race among Latino (χ2 (6.47) = 2, p = .04) and White males (χ2 (11.10) = 2, p = .004). There was no significant difference among Black males (χ2 (2.22) = 2, p = .33). Furthermore, when responding to the questions “Do you want to get to know this girl?” and “Would you message this girl?” (M=_,SD=_) there was a significant preference for same race women among Latino (χ2 (8.40) = 2, p = .004) and White males (χ2 (11.10) = 2, p = .004). There was no significant preference among Black males (χ2

1The purpose of this paper is to perform a chi-square analysis after watching the assigned video. Data taken from a given table will be entered on the SPSS data set with intend to obtain an output. The cross-tabulation table will be highlighted in the output document. Then the highlighted output will be submitted to the instructor.

According to a study, an experiment was done over the course of six years on the growth, needle, carbon, and nitrogen, chlorophyll, and

The average height of the rosette Brassica rapa plants treated with gibberellic acid was 1.98 cm and was taller after 15 days of growth than the rosette Brassica rapa plants treated with water that was 1.17 cm.

From both graphs, the plant with two pellets and six pellets of fertilizer grow faster than zero fertilizer and four fertilizers. Compare to the plant with two pellets and six pellets, the six pellets one grow faster than the plant with two pellets. The plant with four pellets grow slower than the plant with no fertilizer. However, the data doesn’t make sense, so it is unreliable. Also, it does not support the hypothesis. The reason why the data is wrong, is maybe because the Brassica rapa was extract in the first week for measuring the length. Neverthless, it was a wrong action.Therefore,

The control group is the soil from the backyard while the experimental groups are the potting soil and Haw River soil. One cup of soil and five mL of Pennington Tall Fescue grass seed will be placed in each container. Three cups of waters will be given to the grass every other day and the height of the grass will be measured every week. At the end of the experiment, potting soil with 21% nitrogen had the highest grass grown. The backyard soil was the second highest grass grown with 17% nitrogen and Haw River had the shortest grass with 13% nitrogen.

The Figure 6 displays the average values of the internodes lengths of Control plants and Gibberellins affected plants during the experiment.

The summary statistics (median) of all the different samples and the results of the Wilcoxon tests are reported in Table 5.2. The first column shows the median values of all the different variables for the whole sample (all private firms and IPO firms). The P-value of the Wilcoxon tests show the comparison of the median values between the private and public sample. In the next columns you can find the P-values of the Wilcoxon tests for the differences in median values between the private sample and each of the sub-samples (failed, acquired or survivor). The last columns show the P-values for the Wilcoxon tests for the differences in median values between the sub-samples of IPO firms. A proportion test was used to test the difference in the variable RETAIL, which is a binary variable. This tests the difference in percentages.

Many past studies have proven that trifluralin productively inhibits root growth in plants. Researchers have shown that it does this by creating radial enlargement near root tips, which is an effect of altering the polarity of growth of cortical cells. Many investigations have followed to prove whether this chemical also has an influence on mitosis. The studies proved that this herbicide hinders the mitotic process. This study set out to examine this relationship more precisely to identify whether Trifluralin affects Mitosis during Metaphase.

This data shows a strange outcome, in the hypothesis; it says that “If acid is introduced to the seed during germination, then the roots will not grow as long as the seeds that are given water”. This statement proves to be untrue, because the roots grew longer with stronger acid than weaker acid, and in some, cases, grew better with strong acid than it did in water. This may be true because of the acid growth theory. The acid growth theory states that auxins cause the elongation of stem cells by promoting wall loosening. It was determined that this wall loosening is caused by hydrogen ions. This idea and subsequent supporting data gave rise to the acid growth theory, which states that when exposed to auxins, susceptible cells excrete protons into the wall at an enhanced rate, which in turn decreases the pH in the wall. The lowered wall pH then activates the wall loosening process which is essentially doing the same thing as the auxin hormone.

Mitotic division plays a key role in the growth of the root tip of an onion, genus Allium. More specifically, mitosis is responsible for the way in which the root tip elongates. The cells spend a certain amount of time in each stage of mitosis. Assuming a 24hr cycle, the time for each mitotic stage can be calculated as the duration. In Allium, mitosis occurs at different rates in different regions of the root tip. The regions are divided into the region of cell division, elongation, and maturation. The region of cell division can be further divided into zones IA, IB, IC, II, III, and IV.

This specific study investigates an Azatobacter strain, pseudomonas strain and how these two interact on soybean performance. This experiment was designed as a split plot factorial, it also hard a completely randomized design. It used four chemical fertilizers and four levels of plant growth promoting Rhizobacteria. The result was measured by physiological maturity, number of spikes per unit area, harvest index, plant yield, grain yield, plant height, protein content and girth. This article related directly to my experiment because the parameters used to obtain the results of my experiment are similar; also the investigative subject is the same as the one in my experiment. This experiments results showed that if Azatobacter application
