A variable of a population has a mean of μ = 100 and a standard deviation of σ = 28. 1; Describe (tell us about its shape, mean and standard deviation) the sampling distribution of the sample mean for samples of size 49
2; In answering part (1), what assumptions did you make about the distribution of the variable?
3; Can you answer part (1) if the sample size is 16 instead of 49? Why or why not

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).
