PLEASE HELP FAST THANK YOU Suppose the mean
population At
confidence intervals would you expect to contain the population mean?
buted population is 300, and 200 simple random samples are drawn from the
confidence level, (one standard deviation from the mean), about how many of the samples
G6

Step-by-step explanation:

❥❥we rarely know the population standard deviation. In the past, when the sample size was large, this did not present a problem to statisticians. They used the sample standard deviation s as an estimate for σ and proceeded as before to calculate a confidence interval with close enough results. This is what we did in (Figure) above. The point estimate for the standard deviation, s, was substituted in the formula for the confidence interval for the population standard deviation. In this case there 80 observation well above the suggested 30 observations to eliminate any bias from a small sample. However, statisticians ran into problems when the sample size was small. A small sample size caused inaccuracies in the confidence interval

um is there supposed to be a picture?

hi there!

the answer is: 2 and -2

step-by-step explanation:

case 1: an absolute value of positive number will still be a positive number

so absolute value of 2 is 2

case 2: an absolute value of negative number will be positive number so absolute value of -2 is 2
