Using a two-tailed one-sample z-test from a sample of size n, a researcher rejects the null hypothesis as z = 2.0 is greater than the critical value 1.96 at α = .05. What does this mean?
Choose ALL the correct options from the following.
a. As α = .05, the probability that the null hypothesis is correct is less than 5%
b. As α = .05, the probability that the alternative / research hypothesis is correct is more than 95%
c. The result is important as it is statistically significant
d. None of the above

A random sample of n - 16 scores is selecdted from a normal population with a mean of p - 50. After atreatment is administered to the individuals in the sample, the sample mean is found to be M -54 If the population standard deviation is σ-8, is the sample mean sufficient to conclude that the treatment has a significant effect?

To identify the correct Z(critical), it is important to determine whether the hypothesis test is one-tailed or two-tailed. The decision between a one- and two-tailed hypothesis is based on the researcher's expectations about the population from which the sample was selected.

You wonder whether the cohort currently in their mid-20s have had more sexual partners than older generations. Assume that the the average number of...
