3 because Negative numbers equal less than 0. See the number line attached below. In the number line, all the negative numbers are on the left of the zero and all the positive numbers are on the right of the 0.
Answer:
The degrees of freedom are given by:
And the p value would be given by:
For this case we see that the p value is higher than the significance level so we don't have enough evidence to reject the null hypothesis and then the true mean is not significantly different from 7 at the significance level given
Step-by-step explanation:
Data given and notation
represent the sample standard deviation for the sample
sample size
represent the value to test
represent the significance level
t would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean is iequal to 7 or no, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statitic is given by:
(1)
For this case we know that the statistic is:
The degrees of freedom are given by:
And the p value would be given by:
For this case we see that the p value is higher than the significance level so we don't have enough evidence to reject the null hypothesis and then the true mean is not significantly different from 7 at the significance level given
