- Data set presents a sample of the number of defective flash drives produced by a small manufacturing company over the last 30 weeks. The company's operations manager believes that the number of defects produced by the process is less than seven defective flash drives per week. Construct a hypothesis test to verify the operations manager's claim. Hypothesis test should include a t test statistic value, a p value, a decision, and a conclusion. This is the null hypotheses (see attachment): Data: Mean 7.0300 SD 1.3700 SEM 0.2501 N 30Grateful bit of direction with this maths question.

- write about some hypotheses YOU would like to test in the real world. Imagine you were given unlimited time and funding for these endeavors, what hypotheses within the realm of social science do you think would be great to explore? For instance, personally, I would love to test a number of hypotheses in the realm of education. As one example, I’d test the effect of class size on student outcomes. This could be examined with a hypothesis test (Ch. 8), since there is already plenty of established data regarding student grades in the current sized classrooms (which, for my courses is around 45 students). Thus, I could create a study in which a smaller group, perhaps n=10 students, takes the exact same course from me, and compare the mean grade for this treatment group to the population mean of all students in those past larger classrooms. This would, in theory, provide evidence as to whether or not smaller class sizes can increase student success. Unfortunately for me and for you, I don’t…What is the equation for computing the degrees of freedom (df) for a hypothesis test of independence of categorical data?

- MORE BENEFITS OF EATING ORGANIC Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data from this study. In this case, we are testing where p, and p, represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. We have n₁ = n₂ = 500. Show all remaining details in the test, using a 5 % significance level. Effect of Organic Raisins After 20 Days After 20 days, 275 of the 500 fruit flies eating organic raisins are still alive, while 170 of the 500 eating conventional raisins are still alive. ¹Proportions approximated from information given in the paper.
