given a normal distribution with 7.2 Given a normal distribution with u = 50 and o 5, if you select a sample of n 100, what is the probability that X is a. less than 47? b. between 47 and 49.5? c. above 51.1? d. There is a 35% chance that X is above what value?
Given a normal distribution with a mean of 105 and a standard distribution of 25 and given you select a sample of n = 25. There is a 69% chance that X is above what value?
Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0: p = 0.25 vs Ha: p < 0.25 using the sample results p̂p^= 0.13 with sample size n = 100. The standard error of the sample statistic in this situation is 0.043. Round your answer for the test statistic to two decimal places. What is the p-value?...
Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p=0.75 vs Ha : p≠0.75 using the sample results p^=0.69 with n=118 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = p-value = Conclusion:
Given a normal distribution with u = 51 and o = 8, and given you select a sample of n = 100, complete parts (a) through (d). a. What is the probability that X is less than 49?
