A cheerleading squad received a mean rating (out of 100 possible points) of 75 ± 6 ( ± ) in competitions over the previous three seasons. The same cheerleading squad performed in 16 local competitions this season with a mean rating equal to 77 in competitions. Suppose we conduct a one-independent sample z-test to determine whether mean ratings increased this season (compared to the previous three seasons) at a 0.05 level of significance.
(a). State the value of the test statistic. (Round your answer to two decimal places.)
z =
(b). State whether to retain or reject the null hypothesis.
(c). Compute effect size using Cohen's d. (Round your answer to two decimal places.)
d =
