For a one-tailed hypothesis test where you reject Ho only in the lower tail,the critical value is-1.3253.What is the statistical decision if tsTAT=-2.75? What is the statistical decision? OA.Since the tsTAT value is less than the critical value,reject Ho. OB.Since the tsTAT value is greater than or equal to the critical value,do not reject Ho. OC.Since the tsTAT value is less than the critical value,do not reject Ho. OD.Since the tsTAT value is greater than or equal to the critical value,reject Ho.

A researcher conducts a hypothesis test to evaluate the effect of a treatment that is expected to increase scores. The hypothesis test produces a z-score of z = 2.37. If the researcher is using a one-tailed test, what is the correct statistical decision?​Group of answer choices​Fail to reject the null hypothesis with either α = .05 or α = .01.​Reject the null hypothesis with α = .05 but not with α = .01.​This cannot be answered without additional information.​Reject the null hypothesis with either α = .05 or α = .01.

A researcher expects a treatment to produce an increase in the population mean. The treatment is evaluated using a one tailed hypothesis test, and the test produces z = +1.85. Based on this result, what is the correct statistical decision?​Group of answer choices​The researcher should fail to reject H0 with either α = .05 or α = .01.​The researcher should change α.​The researcher should reject the null hypothesis with either α = .05 or α = .01.​The researcher should reject the null hypothesis with α = .05 but not with α = .01.

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
