Tell me if u got it right
Answer:
Step-by-step explanation:
Null hypothesis: u = 9.5hrs
Alternative: u =/ 9.5hrs
Using the t test
t = x-u/sd/√n
Where x is 10hrs, u is 9.5, sd is 1.6 and n is 15
t = 10-9.5 / (1.6/√15)
t = 0.5 / (0.4131)
t = 1.21
In order to make a conclusion, we have to find the p value at a significance level lot 0.1. The p value is 0.2263 which is greater than 0.1. This, we will fail to reject the null hypothesis and conclude that there is not enough statistical evidence to prove that the technique performs differently than the traditional method.

So, we have the area, easy. Multiply each of the answers by 80.
(Hint: You can change the fractions into decimals and do it then. It'll be much easier than trying to multiply it by the fractions.)
25/64=.390625 (I would round this to .39)
25/4=6.25
5/2=2.5
5/8=.625
Which one, when multiplied by 80, gives you 500?
80*.390625=31.25
80*2.5=200
80*.625=50.
Leaving 6.25*80=500. Meaning, 25/4 is your answer.
