Answer:
The degrees of freedom are given by:
The p value can be calculated like this:
For this case since the p value is higher than the significance level we have enough evidence to conclude that the true mean for the wait time is not significantly less than 8 minutes
Step-by-step explanation:
Information given
represent the sampke mean in minutes
represent the sample standard deviation
sample size
represent the value to verify
represent the significance level
t would represent the statistic (variable of interest)
represent the p value
System of hypothesis
For this case we are trying to proof if inspection station advertises that the wait time for customers is less than 8 minutes, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since the population deviation is not known the statistic can be calculated with:
(1)
The statistic for this case is given by:
The degrees of freedom are given by:
The p value can be calculated like this:
For this case since the p value is higher than the significance level we have enough evidence to conclude that the true mean for the wait time is not significantly less than 8 minutes
Answer:
C. 324°
Step-by-step explanation:
We are given that,
The spinner is rotated 180° counter-clockwise about the center and maps J to A.
Since there are 10 sections of the spinner.
So, the angle by each section = = 36°
That is, the angle which maps J to A clockwise is 36°
<h3>Then, the angle which maps J to A counter-clockwise = 360° - 36° = 324°</h3>Thus, option C is correct.
