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?

The given graph represents a population with a Normal distribution. The normal distribution graph shows its peak at x equals 80. The area of the shaded portion of the graph that lies at or above x equals 87 is 0.3085. Which of the statements can we not conclude based on the graph? The proportion of this population that lies at or below ?=87 is 0.3085. The proportion of this population that lies at or above ?=87 is 0.3085. The standard...

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:

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=0.3 vs Ha : p<0.3 using the sample results p^=0.23 with n=202 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 p-value Conclusion:
