An NHANES report gives data for 642 women aged
20
–
29
years. The BMI of these
642
women was
¯
x
=

26.6
. On the basis of this sample, we want to estimate the BMI
μ
in the population of all
20.6
million women in this age group. We treated these data as an SRS from a Normally distributed population with standard deviation
σ
=
7.9
.
(a) Give three confidence intervals for the mean BMI
μ
in this population, using
90
%
,
95
%
,
and
99
%
confidence.

Umm.. just started this 2day and its not on my notes(p′︵‵。)

() at a farm, animals are fed bales of hay and buckets of gain.each bale of hay is in the shape of a rectangular prism.the base side lengths 2 feet and 3 feet,and the height is 5 feet. each bucket of grain is a cylinder with diameter of 3 feet. the height of the bucket is 5 feet as the height of bale. a. which is larger in area, the rectangular base of the bale or the circular base of the bucket? explain how you know b. which is larger in volume, the bale or the bucket? explain how you know

Consider the following equation -167 + 37 = 49 - 21p select the equation that has the same solution as the given equation. o a. p - 5 + ip = 7 - p ob. +55 + 12p = 5p + 16 c. 2 + 1.25p = -3.75p + 10 d. -14 + 6p = -9 - 6p reset next
