Compute the value of z when ƥ = 0.46, q = 0.54, n = 50 and p0 = 0.50.
A random sample of n = 90 kilograms of corn is obtained from a population with μ
= 272 and σ = 5543. Describe the sampling distribution for the sample means by
computing the 𝜇 and 𝜎. (Use the indefinite population) (20 points
Consider a population consisting of 2, 4, 6, 8 and 10. Suppose samples of size 3 are drawn from
this population. a. Describe the sampling distribution of the sample means b. What are the mean and variance of the sampling distribution of the sample means? c. Construct a histogram for the sampling distribution.

- In a plant nursery, the owner thinks that the length of seedlings in a box sprayed with a new kind of fertilizer has an average height of 25cm after. One researcher randomly selected 40 such seedlings and calculated the meanheight to be 28cm and the standard deviation was 8cm.Proceed with the test using a= 0.01
x= 0, 1, 2, 3, 4, 5
p(x)= 0.1,0.3,0.4,0.1,?,0.5
find p(4)
construct probability histogram to describe p(x)
Construct a t-distribution with a sample size of 16 and a confidence level of 97.5%, where
in the critical value is on the left tail
P(−1.2≤z≤1.2)
pls include solutions
