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
i = 3c
i = c + 14
set both equations equal to each-other, we can
solve for c, we must.
3c = c + 14
subtract c from both sides, we must.
2c = 14
divide both sides by 2, we must.
c = 7
