wariber [46]

Answer:

E 0.923

Step-by-step explanation:

The Z score is a measurement used in statistics to determine the relationship between a value and a mean of a group of values measured as standard deviation from the mean. The z score (z) is given as:

$z=\frac{x-\mu}{\sigma}$ , Where μ is the mean, σ is the standard deviation and x is the value.

Given that:

σ = 7, μ = 80 and x = 90

$z=\frac{x-\mu}{\sigma}=\frac{90-80}{7} =1.43$

From the normal distribution table, P(X < 90) = P(z < 1.43) = 0.923
