Here are summary statistics for randomly selected weights of newborn girls: n=167, x=29.6hg, s=6.9hg construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 28.8hg<û<31.4hg with only 14 sample values, x=30.1hg and s=2.7hg? What is the confidence interval for the population mean û?

44

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
