Avoiding an accident while driving can depend on reaction time. That time, measured from the time the driver first sees the danger until the driver gets his/her foot on the brake pedal, can be described by a normal model with mean 1.9 seconds and standard deviation 0.13 seconds. Use the 68-95-99.7 rule (NOT a z table) to answer the following questions. The pictures of the 68-95-99.7 rule at this link might help.

1. write a program using for loop that calculates the total grade for N classroom exercises as a percentage. The user should input the value for N followed by each of the N scores and totals. Calculate the overall percentage (sum of the total points earned divided by the total points possible) and output it as a percentage. Sample input and output is shown below.How many exercises to input? 3
   
   Score received for exercise 1: 10
   Total points possible for exercise 1: 10
   
   Score received for exercise 2: 7
   Total points possible for exercise 2: 12
   
   Score received for exercise 3: 5
   Total points possible for exercise 3: 8
   
   Your total is 22 out of 30, or 73.33%.

a) Construct a 4x2 contingency table that illustrates the relationship between the following two variables: Hospital at which the patient was seen, and whether or not the patient had LDL £ 100 mg/dl. Use the Hospital names as the row headings and whether or not the patient had LDL £ 100 mg/dl as the column headings. Include the overall total as well as row and column totals. Use your table to answer the questions in parts b – e. (Note: Be careful when filling in your table - not all patients have data for these variables. When answering the questions below, use totals from your table.)

b) What percentage of all patients had LDL > 100 mg/dl?

c) What percentage of the patients at VAMC Brooklyn had LDL > 100 mg/dl?

d) What percentage of the patients at VAMC Detroit had LDL > 100 mg/dl?

e) What percentage of the patients having LDL £ 100 were seen at SUNY Brooklyn?

5) Here are summary statistics for randomly selected weights of newborn girls: n=197, x=32.7hg, s=6.7 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 31.6 hg< μ < 34.8 hg with only 12 sample values, x=33.2 hg, and s=2.5 hg? What is the confidence interval for the population mean μ?
