Question
Convert this information on the number of calls to probability distribution. b. Is this an example of a discrete probability distribution? c. What is the mean number of emergency calls per day? d. What is the standard deviation of the number of calls made daily? The director of admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall semester on the basis of past experience. What is the expected number of admissions for the fall semester? Compute the variance and the standard deviation of the number of admissions. Belk Department Store is having a special sale this weekend. customers charging purchases of more than $50 to their Belk credit card will be a special Belk card. be customer will scratch off the card, which will indicate the amount to be taken off the total amount of the purchase. Listed below are the amount of the prize and the percent of amount of the purchase.Explanation / Answer
Given data is
Expected number of admissions for the fall semester
Ans:Expected number of admissions for the fall semester =sum product (admissions,probability)/sum of probabbility
=1,000*0.6+1,200*0.3+1,500*0.1/0.6+0.3+0.1
=1110/1
=1110
The expected number of admissions for the fall semester is 1110
Variance of the number of admissions=VAR(admission values) (using excel function)
=63333.3333
Standard deviation of the number of admissions=stdev(admission values) (using excel function)
=251.6611
Admissions probability 1,000 0.6 1,200 0.3 1,500 0.1
