Answer:
A. Candice should reject the null hypothesis as the 95% confidence interval does not contain 12 hours
Step-by-step explanation:
Given that:
Average watch hour = 12
sample size = 79
The 95% Confidence interval lies between 7.60 and 11.37.
Thus, since the average watch of students in her school does not lie within the interval between 7.60 and 11.37, Candice should reject the null hypothesis.
Answer= Y=-5/3x+7
First substitute (3,2) into the equation y=-5/3x +b which gives you 2=-5/3x+b. Solve for b, then put the equation into slope-intercept form.
Answer:
First step
Step-by-step explanation:
Subtract the 4 to the other side making the equation
(12x+8)+4=3
12x+8=-1
12x=-9
x=-3/4
12+2+8+6+57=85
85/5= 17
mean=17
