As per give , we have
Sample size : n= 20
Degree of freedom : df= n-1=19
Significance level : 
Since , the sample size is small (n<30) so we use t-test.
For confidence interval , we find two-tailed test value.

62 red/blue marbles
62/2=31
31 blue, 31 red
"There are 2 more red marbles than blue marbles."
31-2=29
31+2=33
33/100 red, 29/100 blue.
