I don't understand what you mean but this might be the answer
Here's what I got for the first question.
Did you want answers for the second one? I couldn't read that part of the image very well, if you did.
5x = 1414
x = 1414 / 5
x = 282.80
to find the hypotenuse length you need to use the pythegorian therum and that will give you 29cm
First we need to write the null and alternate hypothesis for this case.
Let x be the average number of text message sent. Then
Null hypothesis: x = 100
Alternate hypothesis: x > 100
The p value is 0.0853
If p value > significance level, then the null hypothesis is not rejected. If p value < significance level, then the null hypothesis is rejected.
If significance level is 10%(0.10), the p value will be less than 0.10 and we reject the null hypothesis and CAN conclude that:
The mean number of text messages sent yesterday was greater than 100.
If significance level is 5%(0.05), the p value will be greater than 0.05 and we cannot reject the null hypothesis and CANNOT conclude that:
The mean number of text messages sent yesterday was greater than 100.
