An advertising firm has decided to ask 115 customers at each of four local shopping malls if they are willing to take part in a market research survey. At . = 0.05 is there evidence to show that the proportions are not all the same. A B D Willing 62 67 69 70 Not Willing 53 48 46 45 What are the expected numbers? (round to 3 decimal places) D Willing Not Willing The hypotheses are Ho : PA = pPB = Pc = Pp HA: At least one of the proportions is different. (claim) Since a = 0.05 the critical value is 7.815 The test value is: (round to 3 decimal places) The p-value is (round to 3 decimal places) So the decision is to do not reject Họ reject H, Thus the final conclusion is There is enough evidence to reject the claim that at least one of the proportions is different. There is enough evidence to support the claim that at least one of the proportions is different. There is not enough evidence to support the claim that at least one of the proportions is different. OThere is not enough evidence…
In 1991, a person was working as an engineer at a paper company when they were laid off in round 2 of several rounds of layoffs by the company. This person sued the company for age discrimination. The engineer claimed that the laid off workers were older than others. The age of randomly selected 10 workers who were laid off and not lay off in round 2 are given below. Test the engineer's claim at 10% level of significance. Note that the data for two samples are in different column.
