Answer:
b<-7 or b>-1
Step-by-step explanation:
explanation: -6b>42 turns into -42>6b then divide by 6 on both sides and you get -7>b

Answer: 1.300228
Step-by-step explanation:
The t-score we use for the confidence interval is two-tailed , i.e. the t-score should be used to find a (
) is given by :-
, where n is the sample size.
Given : Level of confidence: 
Significance level : 
Sample size : n= 47
Then, degree of freedom : 
Now by using standard normal t-distribution table,

Hence, the t-score should be used to find a 80% confidence interval estimate for the population mean = 1.300228
