Answer:
here is the proportion
Step-by-step explanation:
2 = 2/1 = 4/2
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
1/4 + 3/10 = 10/40 + 12/40 = 22/40
40/40 = 22/40 = 18/40
18/40 = cranberry j
Ratio=
A : O : C
10/40 : 12/40 : 18/40
0.25 : 0.3 : 0.45
Answer:
Easy peasy
Step-by-step explanation:
7+(n-1)5
18.56, 18.57, 18.58 or 18.59?
