Information on a packet of seeds claims that the germination rate is 92%. the packet contains 160 seeds.
let p represent the proportion of seeds in the packet that will germinate.
the sampling distribution model for p is:
a. n(0.92, 0.0215)
b. n(0.08, 0.0215)
c. n(147.2, 12.8)
d. n(0.0215, 0.92)

a. N(0.92, 0.0215)

Step-by-step explanation:

For population proportion (p) and sample size n, the mean and standard deviation is given by :-

The sampling distribution model for p is given by :_

, where

We assume that the seeds are randomly selected.

Given : Information on a packet of seeds claims that the germination rate is 92%.

i.e. p= 0.92

The packet contains 160 seeds.

i.e. n= 160

Then ,  

Hence, the sampling distribution model for p is:
