Step-by-step explanation:
Given that during the first 13 weeks of the television season, the Saturday evening 8:00 P.M. to 9:00 P.M. audience proportions were recorded as ABC 29%, CBS 28%, NBC 25%, and independents 18%
H0: Proportion did not change
Ha: Proportions changed
5% significance level is used
ABC CBS NBC INDEP TOTAL
percent 29 28 25 18 100
OBSERVED 90 77 83 50 300
Expected 87 84 75 54 300
chi square 0.103448276 0.583333333 0.853333333 0.296296296 1.836411239
df 3
p value 0.6071
Since p > alpha, we accept null hypothesis
The observed values are as per the proportions.
Answer:
A) y = 3x + 2 y = -2x + 5
Step-by-step explanation:
We can rule out options B and D right away, because one of the lines' y-intercept is positive 2 not negative.
(Remember that y-intercept is the b in y=mx+b).

We can also rule out C though, because the second line's y-intercept is positive 5, while the second line in option C is negative.
You can also use the slope of each line to double check.
Hope this helps :)
