Independent random samples of private college and university
tuition and fees for a recent academic
year from California and New York yielded the following data, in
dollars.
California 29,940 35,650 27,231 21,000 32,610 37,850 36,992 34,584
22,850 25,788
New York 29,283 40,870 28,460 33,835 24,410 30,868 26,400 37,882
22,656 38,980
Construct a 95% confidence interval for μC − μNY , the difference
between the mean amounts of tuition in the two states. Assume that
the population variances for the two states tuitions are equal. Is
there a significant difference in the tuition between the two
states? Explain your answer.
I need this explained by hand, without using minitab.
