Give the distribution of Xˉ. (Enter an exact number as an integer, fraction, or decimal.) Xˉ∼() Part (c) Sketch the graph, shade the region, label and scale the horizontal axis for Xˉ, and find the probability. (Round your answer to four decimal places.) P(Xˉ<60)= Part (d) Find the 40 th percentile. (Round your answer to two decimal places.) Part (e) Sketch the graph, shade the region, label and scale the horizontal axis for Xˉ, and find the probability. (Round your answer to four decimal places.) P(56<Xˉ<62)= Part (f) Sketch the graph, shade the region, label and scale the horizontal axis for Xˉ, and find the probability. (Round your answer to four decimal places.) P(28<Xˉ<59)= Part (g) Give the distribution of ΣX ΣX∼() Part (h) Find the minimum value for the upper quartile for ΣX. (Round your answer to two decimal places.) Part (i) Sketch the graph, shade the region, label and scale the horizontal axis for ΣX, and find the probability. (Round your answer to four decimal places.) P(1400<ΣX<1550)=
