3. Fernanda runs a large bowling league. She suspects that the league average score is greater than 155 per game. She takes a random sample of 40 game scores from the
league data. The scores in the sample have a mean of 158 and a standard deviation of
30. Fernanda wants to use these sample data to conduct a t-test on the mean. Assume
that all conditions for inference have been met. Calculate the t-test statistic.
Answer the following:
a. (1 pt) population mean,
b. (1 pt) sample mean, X
c. (1 pt) sample standard error, sx
d. (1 pt) sample size, n
e. (2 pts) calculate the t-test statistic
