The probability is 51​% that the sample mean will be between what two​ values, symmetrically distributed around the population​
Alisiya [41]

Answer:

The lower bound is, -z=-0.69 and the upper bound is z=0.69.

Step-by-step explanation:

Let the random variable <em>X</em> follows a normal distribution with mean <em>μ </em>and standard deviation <em>σ</em>.

The the random variable <em>Z, </em>defined as Z=\frac{X-\mu}{\sigma} is standardized random variable also known as a standard normal random variable. The random variable  Z\sim N(0, 1).

The standard normal random variable has a symmetric distribution.

It is provided that P(-z\leq Z\leq z)=0.51.

Determine the upper and lower bound as follows:

P(-z\leq Z\leq z)=0.51\\P(Z\leq z)-P(Z\leq -z)=0.51\\P(Z\leq z)-[1-P(Z\leq z)]=0.51\\2P(Z\leq z)-1=0.51\\2P(Z\leq z)=1.51\\P(Z\leq z)=0.755

Use a standard normal table to determine the value of <em>z.</em>

The value of <em>z</em> such that P (Z ≤ z) = 0.755 is 0.69.

The lower bound is, -z=-0.69 and the upper bound is z=0.69.
