Store owner asks 55 people in City A and 50 households in City B whether anyone in their household had used their store's products within the last month. 38 of the households surveyed in City A responded "yes" and 32 households in City B responded "yes." Find the p-value that would be used to make a conclusion for this hypothesis test.

Suppose that in a random selection of 100 colored candies 20% of them are blue. I candy company claims that the percentage of blue candies is equal to 29%. Use a .05 significance level to test the claim. Identify the Noll and alternative hypothesis for this test. And what is the P value?

The magazine Tech Worx reported that 95% of software engineers rate the company they work for as "a great place to work." As a veteran headhunter, you claim the percentage given in the report is not correct. In a survey of 220 randomly chasen software engineers, 208 rated the company they work for as "a great place to work." Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level af significance, to support your claim that the proportion, P, of al software engineers who rate the company they work for as "a great place to work" is nat 93%. (a) State the nul hypothesis H, and the alternative hypothesis A that you would use for the test. H: 0 (b) For your hypothesis test, you will use a Z-test. Find the values of P and n(1-p) to confirm that a Z-test can be used. (One standard is that p2 10 and 1 (1-p)2 10 under the assumption that the null hypothesis is true.) Here is the sample size and P is the population proportion are testing. np =…

* In a certain state, a referendum is being held to determine whether the transportation authority should issue additional highway bonds. A sample of 430 voters is taken in county A, and 235 say that they favor the bond proposal. A sample of 500 voters is taken in county B, and 265 say that they favor the bond issue. Perform a hypothesis test to measure the strength of the evidence that the proportion of voters who favor the proposal is greater in county A than in county B. Use the a=0.02 level of significance. Use P Method and list all 6 steps clearly.
