The accompanying summary data on total cholesterol level (mmol/l) was obtained from a sample of asian postmenopausal women who were vegans and another sample of such women who were omnivores. diet sample size sample mean sample sd vegan 85 5.10 1.05 omnivore 96 5.55 1.20 calculate a 99% ci for the difference between population mean total cholesterol level for vegans and population mean total cholesterol level for omnivores. (use μvegan − μomnivore. round your answers to three decimal places.)

99% CI:

Step-by-step explanation:

We have to calculate a 99%CI for the difference of means for the vegan and the omnivore.

First, we have to estimate the standard deviation

The MSE can be calculated as

The weighted sample size nh can be calculated as

The standard deviation then becomes

The z-value for a 99% confidence interval is z=2.58.

The difference between means is

Then the confidence interval can be constructed as

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
