I need solve this questions

uestion 9 A random sample of 149 full-grown lobsters had a mean weight of 15 ounces. Assume that population Not yet standard deviation is 3.6 ounces. Construct a 95% confidence interval for the population mean. answered Marked out of 5.00 P Flag O a. 14.2 to 15.8 question O b. 14 5 to 15.5 O c. 14.3 to 15.7 O d. 14.4 to 15.6 Question 10 A sample mean is 94, sample size is 27, and population standard deviation is 14 are given. Ho =89, Not yet HI : p /89 and a significance level is 0.10. Use the P-value approach to test the hypothesis. answered Marked out of O a z= 186; P-value = 0.0314; reject null hypothesis 5.00 P Flag O b. z= 1.86; P-value = 0.0628; reject null hypothesis question O c. z= 0.36; P.value = 0.7188; do not reject null hypothesis O d. z = 0.36, P-value = 0.3594; do not reject null hypothesis Question 11 Determine the P-value for a one sided test with t = 1:75 and n=16 Not yet answered Marked out of O a. 0.075 5.00 F Flag O b. 0.05 question O c. 0.0375 O d. 0.0125 on 12 A sample mean of 84.5, sample standard deviation of 11.2, and sample size of 16, Ho p 2 80, HI: p, 80, a=0.01 are given. Use the one-mean t-test to perform the required hypothesis test about the mean, u, of red the population from which the sample was drawn. Use the P-value approach. Also, assess the strength ed out of of the evidence against the null hypothesis. tion O a. Test statistic: t = 1.61 P-value = 0.0075. Reject the null hypothesis. O b. Test statistic t = 161. P-value = 0.075, Reject the null hypothesis. O c. Test statistic: t = 161. P-value = 0.0075. Do not reject the null hypothesis. O d. Test statistic: t = 1.61. P-value = 0.075. Do not reject the null hypothesis
