The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 4004

nydimaria [60]

Answer:

0.8151 is the probability that the weight will be less than 4293 grams.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 4004 grams

Variance = 103,684

$\sigma = \sqrt{103684} = 322$

We are given that the distribution of weight of newborn baby is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(weight will be less than 4293 grams)

P(x < 4293)

$P( x < 4293) \\\\= P( z < \displaystyle\frac{4293 - 4004}{322}) \\\\= P(z < 0.8975)$

Calculation the value from standard normal z table, we have,

$P(x < 4293) =0.8151 = 81.51\%$

0.8151 is the probability that the weight will be less than 4293 grams.
