Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 500 grams while babies born after a gestation period of 40 weeks have a mean weight of 2800 grams and a standard deviation of 395 grams. If a 35-week gestation period baby weighs 2850 grams and a 41-week gestation period baby weighs 3150 grams, find the corresponding z-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.)

The 35-week gestation period baby has a z-score of 0.7.

The 41-week gestation period baby has a z-score of 0.89

Since the 41-week gestation period baby has a higher z-score, he weighs more relatively to his gestation period.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Which baby weighs more relative to the gestation period?

The baby with the higher z-score.

35-week gestation period baby weighs 2850 grams

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 500 grams

This means that Z is found when

The 35-week gestation period baby has a z-score of 0.7.

41-week gestation period baby weighs 3150 grams.

Babies born after a gestation period of 40 weeks have a mean weight of 2800 grams and a standard deviation of 395 grams.

This means that Z is found when

The 41-week gestation period baby has a z-score of 0.89

Since the 41-week gestation period baby has a higher z-score, he weighs more relatively to his gestation period.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
