Two samples are taken with the following sample means, sizes,
and standard deviations
¯x1x¯1 = 30 n1n1 = 58
s1s1 = 3
¯x2x¯2 = 29 n2n2 = 45
s2s2 = 5
Find a 93% confidence interval for difference in means. Note: If
you do not have a Ti-84 and the degrees of freedom is not on Table
F, then please use the =T.INV(Area to left,df) function in
GoogleSheets to find the critical value to 3 decimal places. Round
your interval end points to the nearest whole number.
