Two-tailed, sigma.
13
Left-tailed, mu.
15
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 mean price had decreased when it had not decreased. Type 1 error: The evidence did not lead to the belief that the mean had decreased, when it had in fact decreased.
19
Ho: sigma = 0.7
H1: sigma < 0.7
Type 1 error: The hypothesis was rejected when the true variability is 0.7 psi. Type 1 error: The variability is less than 0.7 psi.
21
Ho: mu = 47.47
H1: mu not equal to 47.47
Type 1 error: The evidence led to the belief that the mean is different than $47.47, but it is not different. Type 1 error: Same as above. #Chapter 10.2. You only need to do the pvalue approach.
