In an effort to study how a womens age effects the rate of calorie burn, 50 individuals heart rates during moderate exercise and weight were measured for each of the six age groups: 20-29, 30-39, 40-49, 50-59, 60-69, and 70-79. This moderate exercise lasted 1 hour. After exercising, each individuals weight was measured. This data was saved in a file called Drill8.mat. Within each variable, the column number represents the age group going from youngest to oldest. In each column are the measured values for all 50 individuals for the age group. Heart rate was measured in BPM and weight was measured in kg.

Part 1

Create a script called FirstName_LastName_HW8.m that loads Drill8.mat and plots the means of heart rate and weight against age group in separate graphs within the same figure. You may represent each age group by its youngest age:

Age = [20, 30, 40, 50, 60, 70].

Part 2

Calories burned in women during moderate exercise can be estimated by the equation:

Calories = (.447*Heart Rate(BPM) - 0.026*Weight(kg) + .074*Age(decades-20.402)*Time(min)/4.184

Plot the mean of calories burned against age group in a separate figure. Is there a positive, negative, or no correlation? Show your answer in the command window using display or fprintf.

Part 3

Create a function called Calories_Burned.m that takes function inputs (dont use input() within the function) of age, weight, heart rate, and the time spent exercising. This function must then output AND display the number of calories burned using the equation above, replacing Age(decades) with Age(years).

Part 4

Using a loop, create a vector that uses Calories_Burned.m to determine how many calories a woman weighing 150kg will burn exercising with a heart rate of 130bpm for 2 hours as they age from 20 to 80. Plot this vector against age.

I don't know how to upload the data file for the weight and heartrate it's a 50x6
