Complete parts .... "0· 41 - 42 '0. P1 - H2 H4: H1 # 42 H1: H1 <H2 What is the test statistic? Number of days to start a business TSTAT = 1.75 (Round to two decimal places as needed.) What is/are the critical value(s)? Select the correct choice below and fill in the answer box within your choice. (Round to two decimal places as needed.)

Reject Ho. There is insufficient evidence of a difference in mean time required to start a business. 6 26 7 7 7 16 21 O B. Do not reject Ho. There is sufficient evidence of a difference in mean time required to start a business. 8 24 3 10 C. Reject Ho. There is sufficient evidence of a difference in mean time required to start a business. D. Do not reject Ho. There is insufficient evidence of a difference in mean time required to start a business. Print Done b. Determine the p-value in (a) and interpret its meaning. p-value = 0.088 (Round to three decimal places as needed.) Interpret the p-value. Choose the correct answer below. O A. The p-value is the probability that two samples, one taken from each of the two populations, have a mean difference equal to the mean difference of these two samples. O B. The p-value is the probability that two samples, one taken from each of the two populations, have a mean difference less than or equal to the mean difference of these two samples if there is a difference in the true population means. O C. The p-value is the probability that two samples, one taken from each of the two populations, have a mean difference greater than or equal to the mean difference of these two samples if there is no difference in the true population means. O D. The p-value is the probability that the null hypothesis is true.
