Astudy studied the birth weights of 1,600 babies born in the united states. the mean weight was 3234 grams with a standard deviation of 871 grams. assume that birth weight data are approximately bell-shaped. estimate the number of newborns who weighed between 1492 grams and 4976 grams. write only a number as your answer. round your answer to the nearest whole number. hint: use the empirical rule.

1527

Step-by-step explanation:

Given: Mean :

Standard deviation :

The formula to calculate the z score is given by :-

For X=1492

The p-value of z =

For X=4976

The p-value of z =

Now, the probability of the newborns weighed between 1492 grams and 4976 grams is given by :-

Now, the number  newborns who weighed between 1492 grams and 4976 grams will be :-

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
