Question

Suppose that the 99% confidence interval (CI) was calculated at lower 99% = -1.82 and upper 99% =0.42

compared to a 95% confidence interval values of lower 95% = -1.309 and upper 95% = -0.091. Anwer the following questions 

i. the lower bound would be (smaller than/larger than/ equal to) the lower bound of 95% CI

ii. the upper bound would be (smaller than/larger than/ equal to) the lower bound of 95% CI

iii. the point estimate would be (smaller than/larger than/ equal to) the lower bound of 95% CI

  •         At 99% CI where B1 hat = -0.7 the critical value is 1.12 and SE is 0.192.
  •         At 95% CI where B1 hat = -0.7 the critical value is 3.184  and SE is 0.192.
Expert Solution
Step 1

Given

The data is as follows:

CL=99%

CI is (-1.82, 0.42)

β^1=-0.7

SE=0.192

 

CL=95%

CI is (-1.309, -0.091)

β^1=-0.7

SE=0.192
