​Plasma-glucose levels are used to determine the presence of diabetes. Suppose the mean ln​ (plasma-glucose) concentration(mg/dL

) in​ 35- to​ 44-year-olds is 4.86 with standard deviation​ = 0.54. A study of sedentary people is planned to test whether they have a​ different, i.e., a​ two-tailed test, level of​ plasma-glucose than the general population. The study will test significance at the 0.05 level. One study indicated that that the mean for the sedentary group will be about 4.96​ mg/dL. How many sedentary people are needed in the study to achieve​ 80% power?

1/3 of the guests chose beef
mario62 [17]
Find the common denominator of 3 and 12 which would be 12.
Then we add the 2 fractions together to get 9/12.
Now we know that 9/12 of the guests chose chicken and beef.
We also know that 69 guests is equivalent to 3/12 which can be simplified down to get 1/4.
So now we can do 69x4 to get 4/4 which is also 12/12, the amount of guests .
69x4 is 276
Your final should be 276.
