Answer: a) Unimodal and symmetric
b) 0.26
c) 0.038
Step-by-step explanation:
Given: Sample size of investors (n)= 131
True proportion of smartphone users(p) =26%
a) Since sampling distribution for the sample proportion is approximately normal when n is larger.
Normal distribution is Unimodal and symmetric.
So correct option : Unimodal and symmetric
b) mean of this sampling distribution = p = 0.26
c) standard deviation of the samplingdistribution = 
Hello there! Provided the information, we know that the nearest multiple of 8 and 9 has to be greater than 50. 8 and 9 do not go into 50.
$9 • 6 hours = $54
$8 • 7 hours = $56
There are 60 minutes in an hour, so we can multiply accordingly:
60 minutes • 6 hours = 360 minutes
60 minutes • 7 hours = 420 minutes
Your final answers are:
It will take John 360 minutes to earn $50.
It will take Amber 420 minutes to earn $50.
(P.S. It takes Amber one more hour to earn $50 than it does for John to earn $50.)
Hope this helps!
