Answer: The confidence interval would be (0.2928,0.3672).
Step-by-step explanation:
Since we have given that
Total number of vehicles = 432
Number of SUVs sold = 142
So, it becomes,
At 90% confidence interval,
z = 1.645
So, the confidence interval would be
Hence, the confidence interval would be (0.2928,0.3672).
Answer:
264x3+171
22x
d. 15.3%
There are a total of 4 + 10 + 7 + 5 = 26 marbles
P(pick a red) = 4/26 = 2/13 = .153 = 15.3%
Its D :)
I just plugged them all in and D was the correct formula
