if u roll a 6 sided die 6 times is it more probable that you will roll all six numbers or that all rolls are the same number? Explain

range is between 294.32 and 227.68 expect the middle 95% of most pregnancies

Step-by-step explanation:

Given data

mean  μ  = 261 days

standard deviation SD = 17 days

most pregnancies = 95%

to find out

In what range expect to find the middle 95% of most pregnancies

solution

we have Z value for 95% is 1.96

so Confidence interval  = mean +/- 1.96×SD

put vale

Confidence interval = 261 +/- 1.96(17)

Confidence interval = 294.32 and 227.68

range is between 294.32 and 227.68 expect the middle 95% of most pregnancies
