Some sources report that the weights of full-term newborn babies in a certain town have a mean of 8 pounds and a standard deviation of 0.6 pounds and are normally distributed. a. what is the probability that one newborn baby will have a weight within 0.6 pounds of the meaning dash that is, between 7.4 and 8.6 pounds, or within one standard deviation of the mean

0.682 is the probability that one newborn baby will have a weight within one standard deviation of the mean.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ =  8 pounds

Standard Deviation, σ = 0.6 pounds

We are given that the distribution of weights of full-term newborn babies is a bell shaped distribution that is a normal distribution.

Formula:

P(weight between 7.4 and 8.6 pounds)

This could also be found with the empirical formula.

0.682 is the probability that one newborn baby will have a weight within 0.6 pounds of the mean.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
