first you need to find the least common denominator which in this case it is 40. since 5 and 8 both go into 40.
5/8 = 25/40
3/5 = 24/40
25/40 - 24/40 =1/40
does this make sense to you?

Answer:
Step-by-step explanation:
Given that x = no of movies high school students watched is N(6.8, 1.8)
Sample size = 36 and hence std error = 1.8/6 = 0.3

(two tailed test)
Mean difference = 6.2-6.8 = -0.6
Test statistic z = -0.6/0.3= -2
p value = 0.02275
Since p <0.05 we reject H0.
There is evidence to show that college students watch fewer movies a month than high school students
The answer would be 4.875
a person or thing that is totally different from or the reverse of someone or something else.
