Question

You wish to test the following claim (HaHa) at a significance level of α=0.02.

Ho:μ=73.3
Ha:μ<73.3

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=106 with a mean of M=72.6. and a standard deviation of SD=5.8.

What is the critical value for this test? (Report answer accurate to three decimal places.)
critical value = ??? steps tI 84

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic = ??? TI 84

The test statistic is...

in the critical region
not in the critical region

please and thank you

This test statistic leads to a decision to...

reject the null
accept the null
fail to reject the null

As such, the final conclusion is that...

There is sufficient evidence to warrant rejection of the claim that the population mean is less than 73.3.
There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 73.3.
The sample data support the claim that the population mean is less than 73.3.
There is not sufficient sample evidence to support the claim that the population mean is less than 73.3.

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.
