Answer:
The degrees of freedom are given by:
the p value for this case would be given by:
For this case we see that the p value is higher than the significance level so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly different from 2564 mm
Step-by-step explanation:
Information given
represent the mean height for the sample
represent the sample standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic
represent the p value
Hypothesis to test
We want to check if the true mean is equal to 2564 mm, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing we got:
The degrees of freedom are given by:
the p value for this case would be given by:
For this case we see that the p value is higher than the significance level so then we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly different from 2564 mm
You have 2 equations here, both already solved for y. Thus, you could eliminate y by equating the two functions. The resulting equation would depend only upon x. Do this. Solve for x. Then, substitute your value for x into either one of the given functions and calculate y. Present your answer in the form (x,y).

The answer is 42 dollars trust me give me brainliest pls
Step-by-step explanation:
I’m a GOAT in math
5 times something must equal 12
12/5 equals 2.4
w=2.4
