A publisher reports that 34% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually less than the reported percentage. A random sample of 190 found that 30% of the readers owned a particular make of car. Is there sufficient evidence at the 0.02 level to support the executive's claim? 1. State the null and alternative hypotheses.
2. Find the value of the test statistic. Round your answer to two decimal places.
3. Specify if the test is one-tailed or two-tailed.
4. Determine the P-value of the test statistic. Round your answer to four decimal places
5. Identify the value of the level of significance.
6. Make the decision to reject or fail to reject the null hypothesis.
7. State the conclusion of the hypothesis test.

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule? (negative amount should be indicated by a minus sign. round your answer to 3 decimal places.) compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) what is your decision regarding h0 ? reject h0 fail to reject h0 compute the p-value. less than 0.01 between 0.01 and 0.025 between 0.025 and 0.05 between 0.05 and 0.10 greater than 0.10
