cts from this specific manufacturer given that their claim is cannot be rejected after you rm hypothesis testing. Therefore, a batch of 16 products are selected and tested. It is that the mean and standard deviation of the sample are 20.5 and 2 cm, respectively. Clearly state the null and alternate hypotheses. Test the above hypothesis using a significance level of 0.05. Should your company purchase from this manufacturer? Also, show your critical region in a standard normal curve. (hint: check the lecture slides) 6. Calculate the p-value and show it on a standard normal curve. Explain your decision regarding the hypothesis test based on the p-value ad compare it to the result in part ii. v. Assume that the company instead claims that the mean diameter of their product is 22 cm. Re-solve the parts i-iii from above. v. Assume that the company has the same claim that the mean diameter of their product does not excel 20 cm but the population standard deviation is unknown. State and null and alternative hypothesis and test it using a significance level of 0.01. Should your company purchase from this manufacturer? (Test the hypothesis)
