A milk processing company test implemented a plant-wide energy conservation program with a goal of reducing the mean daily consumption rate of at least 1,000 kWh from its normal operating plants. The conservation program was implemented in Plant B. The following data was collected on weekdays where consumption level is at its peak. Were the conservation efforts effective in achieving its goal? Compare the results with Plant A’s data where the program is not implemented using α= 0.05. Assume that the population variances are not equal.
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 416 gram setting. It is believed that the machine is underfilling or overfilling the bags. A 21 bag sample had a mean of 407 grams with a variance of 900. Assume the population is normally distributed. A level of significance of 0.02 will be used. Specify the type of hypothesis test.

A study was conducted to identify if there is a significant difference with two brands of shampoo. Random sample A of 25 sheets of shampoo with a mean content of 237 grams and standard deviation of 8.56 grams. Another sample B of 20 sheets pf shampoo showed a mean content of 240 grams and standard deviation of 9.75 grams. Using 0.05 level of significance, conduct hypothesis testing assuming that variances are equal.
An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 210 engines and the mean pressure was 6.7 ibs/square inch. Assume the variance is known to be 0.64. If the valve was designed to produce a mean pressure of 6.8 ibs/square inch, is there sufficient evidence at the 0.1 level that the valve does not perform to the specifications? State the null and alternative hypothesis for the above scenario.
if a researcher undertook an experiment to evaluate the efficacy of a memory enhancement technique among a cohort of 15 college students. The memory recall abilities of each student were assessed both before and after they underwent training in the memory technique. The observed average increase in memory recall scores following the training was 5 points. The sample variance of the differences within the entire sample was denoted as 8. Does this research question aim to ascertain whether there is a statistically significant elevation in memory recall scores after the implementation of the memory improvement training? To address this question, a one-tailed test with a significance level of (alpha = 0.01) is employed.
A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 433 gram setting. It is believed that the machine is underfilling the bags. A 26 bag sample had a mean of 427 grams with a variance of 324. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Make the decision to reject or fail to reject the null hypothesis.
A One-Way ANOVA was conducted and the researcher tested the assumption of homogeneity of variances. How can the researcher test this assumption? Group of answer choices Histograms Shapiro-Wilk test Kolmogorov-Smirnov test Levene’s test
The analysis in Table 10–12 is from a hypothetical study comparing performance of children with communication disorders, their chronological age-matched peers, and their communication age-matched peers. The study had two independent variables: a group variable that was nonexperimental and a method variable that was experimental. The information reported includes descriptive statistics for the three groups of children across the two methods. The inferential data analysis was a two-way analysis of variance (ANOVA) with group and method as the independent variables. First, examine the descriptive statistics. What do you think might have happened in this study? You might consider entering the means in a spreadsheet and generating a bar graph or line graph.
Solve the problem based on the one-factor ANOVA analysis of variance methodology.Based on the information derived from the previous point, respond to the company's Director of Transport. Help yourself with the following questions: • Is there any difference in the times used to transport the cargo from the plant in CDMX to the AICM through the three recommended routes? • Are the standard deviations of each of the chosen pathways the same or different? If they are different, explain what this difference implies in statistical terms. • What type of statistical analysis will you use to answer the question? Justify your answer. • Which test statistic should you use? Why?
