Example 4.7 Data is: 4, 4, 5, 6, 8, 9, 10, find Percentile matching estimate of (c) parameter μ, o2 of Normality distribution

The undergraduate grade point averages (UGPA) of students taking an admissions test in a recent year can be approximated by a normal distribution, as shown in the figure. (a) What is the minimum UGPA that would still place a student in the top 5% of UGPAS? (b) Between what two values does the middle 50% of the UGPAS lie? u= 3.22 \야 0.18| 2.44 Grade point average 3.22 (a) The minimum UGPA that would still place a student in the top 5% of UGPAS is (Round to two decimal places as needed.)

Solve using R commands and manually Suppose that blood chloride concentration (mmol/L) has a normal distribution with mean 104 andstandard deviation 5 (“Mathematical Model of Chloride Concentration in Human Blood,” J. of Med.Engr. and Tech., 2006: 25–30”).(a) What is the probability that chloride concentration equals, less than, and at most 104?(b) What is the probability that someone’s blood chloride concentration level is between 99 and 114?(c) What is the probability that someone’s blood chloride concentration level is above 120?

One year consumers spent an average of ​$22 on a meal at a resturant. Assume that the amount spent on a resturant meal is normally distributed and that the standard deviation is ​$3.Complete parts​ (a) through​ (c) below. a. What is the probability that a randomly selected person spent more than ​$24​?

The undergraduate grade point averages (UGPA) of students taking an admissions test in a recent year can be approximated by a normal distribution, as shown in the figure. (a) What is the minimum UGPA that would still place a student in the top 15% of UGPAS? (b) Between what two values does the middle 50% of the UGPAS lie? 2.48 3.24 Grade point average (a) The minimum UGPA that would still place a student in the top 15% of UGPAs is 3.41. (Round to two decimal places as needed.) H=3.24 0.16 (b) The middle 50% of UGPAS lies between on the low end and on the high end. (Round to two decimal places as needed.) Q G
