The age x and resting heart rate y were measured for ten men, with the results shown in the table.

x 20 23 30 37 35 45 51 55 60 63
y 72 71 73 74 74 73 72 79 75 77

Test, at 10% level of significance, whether age is useful for predicting resting heart rate.

H0:

Ha:

t-Test Statistic (round to three decimal places) =

Critical t-score (t αt α or t α / 2t α / 2, round to three decimal places) =  

Conclusion (write "R" for reject H0, and "F" for fail to reject H0):

Resting Pulse Rate The mean resting pulse rate for men is 72 beats per minute. A simple random sample of men who regularly work out at Planet Fitness is obtained and their resting pulse rates (in beats per minute) are listed below. Use a 0.05 significance level to test the claim that these sample pulse rates come from a population with a mean less than 72 beats per minute. Follow the 5-step example I posted (and the setup in question...

The following code simulates data on resting heart rate vs. age, then simulates running multiple regression analysis repeatedly and saving the coefficients (i.e. slopes) from the model. This model assumes a slightly quadratic relationship between heart rate and age. Copy and run this code, then answer the questions below. n <- 50 coefs_age <- rep(0,1e5) coefs_age2 <- rep(0,1e5) for (i in 1:1e5) { Age=round(runif(n,min=18,max=90)) Age2 <- Age^2 HR <- 84-Age*0.5+Age2*0.035+rnorm(n,sd=15) model <- lm(HR~Age+Age2) coefs_age[i] <- summary(model)$coefficients[2,1] coefs_age2[i] <- summary(model)$coefficients[3,1] }...

1) The average resting heart rate for a healthy adult horse in the population is 46 beats per minute, with a standard deviation of 8 beats per minute. A horse whose resting heart rate is in the upper 5% of the distribution may be at risk for a serious illness. If your house has a resting heart rate at 58 beats, would you consider your horse to be at risk? To Answer this CALCULATE the Z score for that heart...
