Reference no: EM13109659

Use the p value method to determine whether or not to accept or reject the null and alternate hypotheses.

1. You are determining whether the true mean is less than 11 with a 95% confidence based on the following statistics:

n(sample size) = 14 sample mean = 9 sample st. dev = 4

2. You are trying to determine whether the true mean is not equal to 10, with a 95% confidence based on the following descriptive statistics.

n = 14 sample mean = 12 sample st. dev = 3

3. You are trying to determine whether the true mean is greater than 1 with a 96% confidence based on the following descriptive statistic:

n = 16 sample mean = 3 population st. dev = 4
