Exam Question 2 A local restaurant has studied the behavior of its clients to predict during which time of day they will be the busiest. Given below is a continuous probability distribution that shows the capacity rate for various times of day.   Write a sentence describing the shaded region on the graph in context. Note that you do not need to find the area of the shaded region.   Write the probability notation for the shaded region on the graph above. Shade the region on the graph that corresponds to the capacity rate of the restaurant after 8 pm. Find the capacity rate at the restaurant before 8 pm using the complement rule. Write probability notation and the calculation in your answer. Around what times of day are the busiest? Explain why you think this.

Prof Rea’s Exam Question 2. A restaurant is deciding which farm to order berries from for a seasonal dessert on their menu. The average cost for a pound of berries in California is $2.82 with a population standard deviation of $0.45. Assume that berry cost in California is normally distributed. Suppose that farms in California sell 10 different kinds of berries.  Explain why the sampling distribution of sample means is approximately normal.  Compute the mean,

Exam Question 3 The systolic blood pressure (given in mm Hg) of females has an approximately normal distribution with mean µ = 125 and standard deviation σ = 11. Label the tick marks on the horizontal axis using what you know about the normal distribution and noting that the distance between each tick mark is 1 standard deviation. Adam says that . Describe three mistakes that Adam made. Then explain to him how to fix them. Identify the systolic BPs that encompass approximately 95% of all systolic BP’s of females. Explain why.
