Please note that this question consists of five parts. You may use MINITAB to find a final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question.  A cookie company claims that more than 60% of the cookies in their mixed cookie boxes are chocolate chip. A customer suspects this might not be true. To test the customer’s question, a box of cookies was randomly selected and the number of chocolate chip cookies was counted. Out of 70 cookies, 38 turn out to be chocolate chip. Set up appropriate null and alternative hypotheses that answers customer’s question. Are the conditions to carry out the above test satisfied? Show your work for checking the conditions rather simple “yes” or “no” answer. Calculate the test statistic (show the mathematical work) Calculate the p value for the test. You may use MINITAB to find the numerical value of the p value for the test. However, you MUST clearly write down the probability statement Write the final conclusion in the context of the problem (use 5% significance level). 

For each statement about hypothesis testing for the population mean, state if it is true or false. 

T distribution is symmetric around 0. This is a statement. For a t distributed random variable T,  

The administration of a large university is planing on increasing the student fees with the intention of using majority of the funds towards renovations in the football stadium. In a random sample of 60 students, 38 support of the idea. A 90% confidence interval for the true proportion of students who oppose this idea is 

If one fails to reject the null hypothesis, then they could have made
