For a random sample of 46 University of Maryland undergraduate students, the mean amount of sleep last night equal 6.8 hours with a standard deviation of 1.3 hours. What would the boundaries for a 99% confidence interval to estimate the mean amount of sleep last night for all UMD undergraduate students equal

the answer is d

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

the answer on e2020 was d.
