Sveta_85 [38]

Answer:

1/10

Step-by-step explanation:

add 2/5 and 1/2 then subtract from 1 whole to find the remainder

make it so they have the same denominator

2/5 = 4/10

1/2 = 5/10

4/10 + 5/10 = 9/10

1=10/10

10/10-9/10 = 1/10

so 1/10 of the students don't exercise at all

Answer:

No, we cannot conclude anything about 0.10

Yes, they have made the same decision.

Step-by-step explanation:

Consider the provided information.

Part (A)

They based this conclusion on a test using α = 0.05. Would they have made the same decision at α = 0.10

A significance level of 0.05 indicates a 5% risk of concluding that a difference exists

From the normal table the critical value is Z(0.05) = 1.645 and we accept null hypothesis.

If α = 0.1, the critical value is Z(0.1)=1.28

1.28 is less than 1.645.

Therefore, we cannot conclude anything about 0.10

Part (B)

α = 0.01, the critical value is Z(0.01)=2.33

The critical value of α = 0.05 is 1.645 which is less than 2.33,

So we would again reject the null hypothesis.

Hence, they have made the same decision.
