I need solve this questions MCQ of Statistics

Q5 Q6 Expedia would like to test the hypothesis that A sample mean is 137, sample size is 20, and the proportion of United Airline flights that population standard deviation is 14.2 are arrive on-time is less than 0.80. A random given. Ho: =132, H1 : u#132 and a significance sample of 110 United Airline flights found that level is 0.05. Use the P-value approach to test the 82 arrived on-time. Expedia would like to set a = hypothesis. 0.02. Which one of the following statements is true? O a. Because the p-value is less than a, we O a. z = 2.57; P-value = 0.0101; reject null reject the null hypothesis and conclude that the proportion of United Airline hypothesis flights that arrive on-time is less than O b. z = 0.35; P-value = 0.7263; do not reject 0.80. null hypothesis O b. Because the p-value is greater than a, we reject the null hypothesis and cannot O c. z = 1.57; P-value = 0.0582; do not conclude that the proportion of United reject null hypothesis Airline flights that arrive on-time is less than 0.80. O d. z = 1.57; P-value = 0.1164; do not reject null hypothesis O c. Because the p-value is less than a, we fail to reject the null hypothesis and cannot conclude that the proportion of United Airline flights that arrive on-time Flag question is less than 0.80. Q20 O d. Because the p-value is greater than a, we fail to reject the null hypothesis and A medical school claims that more than 28% of cannot conclude that the proportion of its students plan to go into general practice. It is United Airline flights that arrive on-time found that among a random sample of 130 of the is less than 0.80. school's students, 39% of them plan to go into Q7 general practice. Find the P-Value for testing The alternative hypothesis, denoted by HI, the school's claim. represents the opposite of the null hypothesis and is believed to be true if the null hypothesis O a. 0.3461 is found to be false. O b. 0.0280 Select one: O C. 0.0026 O True O d. 0.1635 O False
