Question 211119: Based on the information given for each of the following studies, decide
whether to reject the null hypothesis. For each, give the Z-score cutoff (or cutoffs)
on the comparison distribution at which the null hypothesis should be rejected,
the Z score on the comparison distribution for the sample score, and
your conclusion. Assume that all populations are normally distributed
Population
Sample Tails
Study μ σ Score p of Test
A 5 1 7 .05 1 (high predicted)
B 5 1 7 .05 2
C 5 1 7 .01 1 (high predicted)
D 5 1 7 .01 2

-------------------
Let me get this straight:
mean = 5, standard dev. = 1, alpha = 5%, ?? p-value = 1??
---
How can the p-value be 1?
What do you mean by "high predicted"?
