Question

A recent survey of 1000 American women between the ages of 45 and 64 asked them what medical condition they most feared. Of those sampled, 61% said breast cancer, 8% said heart disease, and the rest picked other conditions. By contrast, currently about 3% of female deaths are due to breast cancer, whereas 32% are due to heart disease?a. Construct a 90% confidence interval for the population proportion of women who most feared breast cancer. Interpret.b. Indicate the assumptions you must make for the infer- ence in part a to be valid.

Answer 1

Answer:

Confidence interval for the population proportion of women fearing from breast cancer are 61%

Step-by-step explanation:

Point estimate of the proportion of the population of women who feared from breast cancer is:

β=61%

Standard error of the estimate:

Se= 0.154

Margin of error for 90% confidence interval for the population proportion:

0.254

90% confidence interval for the population proportion will be

(0.5846,0.6354)
