- Sample size requieraThe degrees of freedom is critical to computing the p-value for the chi-square goodness of fit. We will discuss the p-value in the next lab. The degrees of freedom for the Chi-Square goodness of fit is equal to (the number of non-zero rows in the table) - 1. The number of non-zero rows is the number of expected values that are non-zero. For example: Phenotype ... Expected ... Disease ... 234 ... Wild-type ... 6743 ... has two rows where the Expected value is non-zero. So the degrees of freedom is 2-1 = 1. Another example: Phenotype ... Expected ... Disease ... 2374 ... Wild-type ... 0 ... has one row where the Expected value is non-zero. So the degrees of freedom is 1-1 = 0. With 0 degrees of freedom, the chi-square test cannot be calculated. A third example (sex-linked): Phenotype ... Expected ... Disease-Male ... 2374 ... Disease-Female ... 9456 Wild-type-Male ... 1001 ... Wild-type-Female ... 235 ... has four rows where the Expected values are…R7 An experiment is to be carried out with three different drugs for treating migraine. 16 patients of similar age, health condition and migraine problems are identified.

- Homer Simpson is interested in studying the ratio of the various colors of sprinkles on Lard Lad donuts. To conduct his study, Homer purchases three of each variety of donut they make and counts the sprinkles on them. What method did Homer use to select his sample? 1. Stratified 2. Simple Random Sample 3. SystematicCharacter recognition An automatic character recogni-tion device can successfully read about 85% of hand-written credit card applications. To estimate what might happen when this device reads a stack of applications, thecompany did a simulation using samples of size 20, 50,75, and 100. For each sample size, they simulated 1000samples with success rate p = 0.85 and constructed thehistogram of the 1000 sample proportions, shown here.Explain how these four histograms demonstrate what the Central Limit Theorem says about the sampling distribu-tion model for sample proportions. Be sure to talk about shape, center, and spread.Find the F-test and T-test (T-test calculated and T- table) of sample A and B using the data.
- Big Blossom Greenhouse was commissioned to develop an extra large rose for the Rose Bowl Parade. A random sample of blossoms from Hybrid A bushes yielded the following diameters (in inches) for mature peak blooms. 2 in, 3 in, 3 in, 8 in, 10 in, 10 inMagnetic surveying is one technique used by archaeologists to determine anomalies arising from variations in magnetic susceptibility. Unusual changes in magnetic susceptibility might (or might not) indicate an important archaeological discovery. Let x be a random variable that represents a magnetic susceptibility (MS) reading for a randomly chosen site at an archaeological research location. A random sample of 120 sites gave the readings shown in the table below.Chi-square test for k Independent Samples
- A chi square test for independence and homogeneity is appropriate if: Select one: a. the data is normally distributed b. the sample size is greater than 30 c. the expected frequency in each cell is 5 or greater d. the expected frequency in each cell is less than 5In a test of significance, if all else is held constant, what can be done to increase the power of a test? Decrease the sample size. Decrease the significance level. Decrease the sample size or decrease the significance level. Increase the sample size or increase the significance level.hw 10 Based on the histogram above, what is the class width?Class width = What is the sample size?Sample size =
