Use a t-test to test the claim about the population mean p at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: p 2 8000; a = 0.10 Sample statistics: x = 7700, s=480, n=22 What are the null and alternative hypotheses? O A. Ho: p# 8000 O B. Ho: p 28000 He: p = 8000 He: p 8000 What is the value of the standardized test statistic? The standardized test statistic is . (Round to two decimal places as needed.) What is the P-value? P= (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O A. Fail to reject Ho- At the 10% level of significance, there is enough evidence to reject the claim. O B. Reject Ho- At the 10% level of significance, there is not enough evidence to reject the claim. O C. Fail to reject Ho- At the 10% level of significance, there is not enough evidence to reject the claim. O D. Reject Ho- At the 10% level of significance, there is enough evidence to reject the claim
