Answer:
The degrees of freedom are given by:
And the p value would be given by:
And since the p value is lower than the significance level we have enough evidence to conclude that the true mean for this case is significantly hiher than 4. And the claim for this case is not appropiate
Step-by-step explanation:
Data provided
represent the sample mean for the weigths
represent the sample standard deviation
sample size
represent the value that we want to analyze
represent the significance level for the hypothesis test.
t would represent the statistic
represent the p value for the test
System of hypothesis
We want to conduct a hypothesis in order to check if the true mean weigth is less than 4 or not, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
Replacing the info given we got:
The degrees of freedom are given by:
And the p value would be given by:
And since the p value is lower than the significance level we have enough evidence to conclude that the true mean for this case is significantly hiher than 4. And the claim for this case is not appropiate
