Ho: p = .105

H1: p > .105

Type 1 error: Determining the true proportion p is greater then .105 when it is not.

Type 1 error: Determining the true proportion p is not greater then .105 when it is.

17

Ho: mu=218,600

H1: mu<218,600

Type 1 error: Determining the true mean mu is smaller than 218,600 when it is not.

Type 2 error: Determining the true mean mu is not smaller than 218,600 when it is.

19

Ho: Theta=0.7

H1: Theta<0.7

Type 1 error: Determining the true Theta is smaller than 0.7 when it is not.

Type 2 error: Determining the true Theta is not smaller than 0.7 when it is.

21

Ho: mu=47.47

H1: mu not=47.47

Type 1 error: Determining the true mu is equal to 47.47 when it is not.

Type 2 error: Determining the true mu is not equal to 47.47 when it is.

Chapter 10.2. You only need to do the pvalue approach.

7

np(1-9) is greater then or equal to 10.

The Pvalue = .0104

Reject the Null Hypothesis.

9

np(1-p)=37.1 and that is greater than 10.

The Pvalue=0.2296

Does not reject the Null Hypothesis.

11

np(1-p)=45 and that it is greater than 10.

The Pvalue = 0.1362

Does not reject the Null Hypothesis.

13

27 people in 100 will give higher than the true 0.5. It does not reject the Null Hypothesis.

15

The Pvalue = 0.2578

Does not reject the Null hypothesis

17

The Pvalue = 0.1379

Does not reject the Null Hypothesis

19

The Pvalue = 0.0047

It rejects the Null Hypothesis.
