In a study of exercise, a large group of male runners walk on a treadmill for six minutes. Their heart rates in beats per minute at the end vary from runner to runner according to the (104,12.5) distribution. The heart rates for male nonrunners after the same exercise have the (130,17) distribution.
(a) What percent of the runners have heart rates above 140?

Answers

Answer 1

Percentage for the runners with heart rate of above 140 is 50.199% probability.

How to calculate heart rate probability?

To calculate percentage of runners heart rate;

Mean, μ = 104

Standard deviation, σ = 12.5

Probability = P(X > 140)

P(X > 140) = [tex]1 - P (\frac{X - μ}{σ} \leq \frac{140 - μ}{σ})[/tex]

P(X > 140) = [tex]1 - P (Z \leq \frac{140 - 104}{12.5})[/tex]

P(X > 140) = [tex]1 - P (Z \leq \ 2.88)[/tex]

For a Z score of 2.88, the cumulative from mean probability and percentile are:

The normal distribution for 2.88 = 0.49801

P(X > 140) = 1 - 0.49801

P(X > 140) = 0.50199

P(X > 140) = 0.50199 x 100

The percentage for the heart rate = 50.199%

The probability of of runners heart rate above 140 is a 50.199% chance.

Given the simple linear regression model y=b0+b1xi+µ the drive the error variance

Answers

The error variance can be Illustrated as σ^2 = E(μ^2) = Var(μ) = (1/n) * ∑(y - (b0 + b1x))^2

How to illustrate the error variance?

The simple linear regression model is of the form:

y = b₀ + b₁x + μ

y = the dependent variable

x = the independent variable

b₀ and b₁ = the parameters of the model, and μ is the error term.

The error term represents the difference between the observed value of the dependent variable and the value predicted by the model. In other words, it is the deviation of the observed y from the expected value of y, given the value of x.

The error variance, denoted by σ^2, is a measure of the spread of the error term. It is calculated as the average squared deviation of the error term from its mean value, which is zero:

σ^2 = E(μ^2) = Var(μ) = (1/n) * ∑(y - (b₀ + b₁x))^2

Alan, you have been tenacious and have had such a great attitude in the face of so many setbacks.
