5- A hospital buys blood pressure monitors in lots of 1000. On average, 2 out 1000 is defective. If 10 are selected from one lot a. What is the probability that none is defective? b. What is the probability that the first two are defective? c. What is the probability that exactly three are defective? d. What is the probability 6- Find the mean, mode, median, and standard deviation for the following data set: {14, 17, 13, 16, 15, 12, 13, 12, 14}

Solutions

Expert Solution

Ans 5) X follow poission distribution with lemmda=10*0.002=0.02

Ans 6) firstly arrange data in ascending order mid value is median

median =14

Mean=14

Mode=14

Standard deviation =1.67

Solution file is attached go through it

A study was conducted concerning blood pressure of 65-year-old men with glaucoma. The average blood pressure in 65-year-old men is 110mmHg. In the study, 144 65-year-old men with glaucoma are randomly selected and the sample mean blood pressure was 120 mmHg and the sample standard deviation is 15 mmHg. Test the claim that this sample comes from a population with blood pressure that is 110 mmHg, and state your decision.
