statistics The manager of a fast-food restaurant claims that the average waiting time at their drive-through fromthe time an order is placed to the time the order is received does not exceed 180 s. A customer wouldlike to test this claim. She conducted an investigation by taking a random sample of ten orders andmeasured the waiting times (in seconds). The results are as follows.208193175195170167195180186172Do an appropriate test of hypothesis to determine if themanager's claim is valid at 5% level of significance. Assume thatthe waiting times follow the normal distribution.A. Perform a complete test of hypothesis.B. Select here the conclusion for this test of hypothesis.There is no sufficient evidence to say that the average waiting time at their drive-through from the time an orderis placed to the time the order is received exceeds 180 s. The manager's claim can not be rejected.The manager's claim is false. The average waiting time at their drive-through from the time an order is placed tothe time the order is received exceeds 180 s.

Given data is 208,193,175,195,170,167,195,180,186,172sample size(n)=10significance level(α)=5%=0.05

In manufacturing processes, it is of interest to know with confidence the proportion of defective parts. Suppose that we want to be reasonably certain that less than 4 % of a company's widgets are defective. To test this, we obtain a random sample of 250 widgets from a large batch. Each of the 250 widgets is tested for defects, and 6 are determined to be defective,based upon the manufacturers standards.using a= 0.01, is this evidence that less than 4% of the company's widgets are defective? State the hypothesis, list and check the conditions, calculate the test statistic, find the p-value, and make a conclusion in a complete sentence related to the scenario.
