There is enough evidence to infer at the 10% significance level that the population mean is greater than 23
Step-by-step explanation:
Given that the sample mean is 26 and sample std dev = 9
i.e
(Right tailed test at 10% significance level)
Mean diff = 3
Test statistic t =
Critical region is t>1.310
df 31
p value = 0.034
Since p <0.10 reject null hypothesis
There is enough evidence to infer at the 10% significance level that the population mean is greater than 23
Critical region is in the enclosed file
2/3x = 6/7 - 1/2
2/3x = 12/14 - 7/14
2/3x = 5/14
x = 5/14 . 3/2
x = 15/28
