b)
c)
And the 90% confidence interval for the true proportion is given by (0.527;0.593).
Step-by-step explanation:
Part a
For this case we don't have any prior info given so then the probability assumed for this case is:
Part b
For this case the proportion of success is given by:
Part c
The confidence interval for the true proportion would be given by this formula
For the 90% confidence interval the value of and , and the critical value would be given by:
The confidence interval is given by:
And the 90% confidence interval for the true proportion is given by (0.527;0.593).
Answer:
A
Step-by-step explanation:
3(14║-10+3║)-║8-2║^2=3(14-║-7║)-║8-2║^2=3(14-7)-6^2=3(7)-36=21-36=-15
Answer:
its -5 I think
Step-by-step explanation:
Last step...
8x = 80 ---divide both sides by 8 ---division property
