A sample of n = 16 individuals is selected from a population with a mean of 60 and a standard deviation of 6 and a treatment is administered to the sample. After treatment, the sample mean is 63. What is the value of Cohen’s d for this sample?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4

Don’t know sorry about that
