Assume the population is normally distributed

12) Based on a recent trip to Las Vegas, Big Daddy claims his career average amount won per
session playing video poker is $250. Big Daddy doesn't have all of his previous results so he
takes a sample of 7 sessions from his recent trip that yielded the following data: x = $280,
and s = $30. Assume the population is normally distributed. Given that a = .05, find the test
statistic, and state the conclusion.
A) Test Statistic: t = 2.646
B) Test Statistic:
Decision:
t = 2.646
Fail to Reject Ho
Decision:
Reject Ho
C) Test Statistic:
t = -2.646
Decision:
Reject Ho
D) Test Statistic:
Decision:
t = -2.646
Fail to Reject Ho

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
