The p value of the test when the cell phone user wants to determine what data plan she should get is 0.1324.
<h3>What is a P value?</h3>
The p-value is a figure that, when generated from a statistical test, indicates how likely it is that, if the null hypothesis were true, you would have discovered a certain collection of observations. In order to determine whether to reject the null hypothesis, P-values are utilized in hypothesis testing.
The following can be deduced from the information:
Number = 15
Mean = 11.25
Standard deviation = 2.5
Test statistics = -1.162
This is the left tailed test.
The p value will be:
P(z < -1.162 )
This will be looked at in the distribution table
= 0.1324
P-value = 0.1324
