Question
testing the hypothesis H,- 100 vs. H : > 100, the p-value is found to be 0.074, and the mean is 105. Which of the following statements is true? A) The probability ofobserving a sample mean at least as large as 105 from a population whose mean is 100 is 0.074 B) The probability of observing a sample mean smaller than 105 from a population whose mean is 100 is 0.074 C) The probability that the population mean is larger than 100 is 0.074. D) The probability that the population mean is larger than 105 is 0.926. E) The probablity that the population mean is smaller than 100 is 0.074.Explanation / Answer
P-value shows the probability of finding the sample results under the assumption that null hypothesis is true.
That is 0.074 shows the probability of observing of the sample mean greater than 105 such that null hypothesis is true.
Correct option is A.
