after checking the hypothesis tests, please explain briefly how you should proceed given the result of recent hypothesis tests and what the owner should do Problem: Mr. Kinalabaw, an owner of a mango plantation, is worried about theincreasing number of fruit piercing moths present in most of the mango trees in hisfarm. He then asked for Concon's help, his trusted statistician, in resolving theproblem. They identified two types of pesticide (1, 2) and two methods ofapplication (A, B). They applied each treatment combination to 3 fruit piercingmoths.

A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 5% margin of error at a 90% confidence level, what size of sample is needed? Give your answer in whole people.
You and a friend are interested in knowing if two groups have the same proportion of smokers. The first group of n = 500 consist of 490 smokers. The second group of n = 500 has 400 smokers. The overall proportion of smokers in both groups is .89 (89%). You want to know whether the proportions of smokers are the same in the two groups of individuals. Based on a 95% confidence level, after hypothesis testing, what would you tell your friend? Would the null hypothesis reject H0 or fail to reject H0?

A marketing agency wanted to determine if a new commercial changed people's opinion about a company. They recruited n=30 participants to watch the commercial. First, everyone was givien a survey to determine their attitudes toward the company. Then, everyone watched the new commercial. Finally, they were given the same survey again and asked about their attitudes toward the comapny after seeing the commercial. The agency wanted to see if attitudes were changed by the commercial. What statistical test should they use?

The magazine Tech Worx reported that 89% of software engineers rate the company they work for as "a great place to work." As a veteran headhunter with extensive experience in the tech industry, you claim the percentage given in the report is not correct. You will test your claim by performing a hypothesis test. To do so, you survey 225 randomly chosen software engineers. Of those surveyed, 216 rated the company they work for as "a great place to work."

The Bureau of Labor Statistics reports that the official unemployment rate for Black people was 10.4% and 4.7% for White people in February 2015. Select all correct answers for this question. O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.
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…
