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 = 

Answer:
-6x^6y^5
Step-by-step explanation:
you have to find p such that
(-3
y)(p) = 18
So just divide to find p
p =
= -6
