Expert Solution

We have here for given example,

Sample mean for difference=-1.01
Sample standard deviation for difference=1.2
Sample size=13
Degree of freedom =n-1=12

Level of significance =0.07

t critical value (by using t table) =1.989

Confidence interval upper limit for paired t test is

=-0.348

Upper limit for confidence interval is= -0.348

Use student-t to derive the following paired test set.seed(20) girls_height<- rnorm(50, mean = 160, sd = 30) boys_height<- rnorm(50, mean = 172, sd = 30) #------------------------------------------------------------- State the hypothesis for the paired-test of the mean of # girls' height and boys' height. Check the three assumptions before running the student t test # for the samples. You need to write and run the code, and # report the results.
