Using the t-distribution, it is found that the value of the test statistic is t = -87.3.
At the null hypothesis, it is <u>tested if the mean is of 2,463 square feet</u>, that is:
At the alternative hypothesis, it is <u>tested if the mean is smaller</u>, that is:
.
We have the <u>standard deviation for the sample</u>, hence, the <em>t-distribution</em> is used to solve this question.
The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
- n is the sample size.
The values of the <em>parameters </em>are: .
Hence, the value of the <em>test statistic</em> is:
