10. We measure head weight of 50 humans and find that the average head weight is 3.75kg with a standard deviation of 0.56kg. Find t*. the answer is t* = -12.63 , i want to know how to do this though
Assuming your alpha was 0.05, what is the t-table value for the human head data?
t = 2.021 (remember to round down for the df, df = 49 so look up df = 40)
- What is your decision about the hypotheses? Reject H0 or Fail to Reject H0.
Since t* is more extreme than t-table, we Reject H0
- Write a concluding sentence about head weight.
Because we rejected H0, we conclude that the mean population head weight is not 4.75kg
I have included answers , I want explanations though

What is normal, when it comes to people's body temperatures? A random sample of 130 human body temperatures had a mean of 98.15° and a standard deviation of 0.74°. Does the data indicate that the average body temperature for healthy humans deviates from 9

Total blood volume (in ml) per body weight (in kg) is important
in medical research. For healthy adults, the red blood cell volume
mean is about μ = 28 ml/kg.† Red blood cell volume that is

Homework problem 50 involves both regression and correlation so we refer to the key elements in both section 10-1 and 10-2. I used a spreadsheet that I developed for another problem with the data provided to find the regression line for predicting the depth of an earthquake from its magnitude. I have attached my spreadsheet. The plot shows a lot of scatter in the data and the calculated linear correlation coefficient r is low: -0.047. We are asked to estimate...

Would Not Approve of Driving Drunk Would Not Approve of Driving Drunk n1=40 n2=25 X¯1=2.1 X¯2=8.2 s1=1.8 s2=1.9 John Worrall and colleagues (2014) found that the fear of losing the good opinion of one’s family and peers kept people from driving home drunk. Let’s say we have two independent random samples of people: those who think that their peers would disapprove of them from driving drunk, and those who think that their peers would either not care or approve of...
