Construct a 99% confidence interval of the population proportion at the given level of confidence. x=240, n=300 the lower bound is? the upper bound is?

lower bound = 0.7404; upper bound = 0.8596

Step-by-step explanation:

The proportion p for this population:

p =

p = 0.8

Confidence interval for proportion is calculated as:

p ± z-score.

Z-score for a 99% confidence interval is: z = 2.58

Calculating:

0.8 ± 2.58.

0.8 ± 2.58.

0.8 ± 2.58(0.0231)

0.8 ± 0.0596

This means that the lower limit of this interval is 0.7404 and upper bound is 0.8596

step-by-step explanation:

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
