Refer to question in Salkind's chapter 11 (its asking you to perform t tests by hand for three parts a, b, and c). Instead provide a calculation (Show your work) of the effect sizes for each of the parts and interpret what they would mean.

1. Question in Salkinds chapter 11: Time for some tedious, by hand practice just to see if you can get the numbers right. Using the following information, calculate the t-test statistics by hand

a. X1= 62, X2= 60, n1=10, n2=10, s1=2.45, s2=3.16

b. X1= 158, X2= 157.4, n1=22, n2=26, s1=2.06, s2=2.59

c. X1= 200, X2= 198, n1=17, n2=17, s1=2.45, s2=2.35
