Here are summary statistics for randomly selected weights of newborn girls: n=204, x=26.9 hg, s=6.9 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 26.0 hg< μ <28.4 hg with only 14 sample values, x =27.2 hg, and s=2.6 hg?

40 minutes

step-by-step explanation:

add the time and multiply by 2

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

is there supposed to be a diagram or a graph for this one? ?
