Question 3Assume your null hypothesis is μ = 6. In your sample you find a value that is lower than 6. Is it 'easier' to reject the null hypothesis with a one-tailed or two-tailed test?1 point A one-tailed test. A two-tailed test. This depends on the level of significance. This depends on the P value.

In testing the hypothesesH0: μ = 75.HA: μ < 75,the p-value is found to be 0.042, and the sample mean is 80. Which of the following statements is true?Group of answer choicesNone of the above statements is correct.The probability of observing a sample mean at most as large as 75 from a population whose mean is 100 is 0.042.The probability that the population mean is smaller than 75 is 0.042.The smallest value of α that would lead to the rejection of the null hypothesis is 0.042.

For a one-tailed hypothesis test (upper tail) the p-value is computed to be 0.034. If the test is being conducted at 95% confidence, the null hypothesisQuestion 7Select one:a.could be rejected or not rejected depending on the sample sizeb.is rejectedc.could be rejected or not rejected depending on the value of the mean of the sampled.is not rejected

A two-tailed test is performed at a 5% level of significance. The p-value is determined to be 0.09. The null hypothesisGroup of answer choiceshas been designed incorrectlymust be rejectedshould not be rejectedmay or may not be rejected, depending on the sample size
