Question

An obstetrician read that a newborn baby loses on average

ounces in the first two days of his or her life. He feels that in the hospital where he works, the average weight loss of a newborn baby is less than

ounces. A random sample of

newborn babies has a mean weight loss of

6.2

ounces. The population standard deviation is

1.5

ounces. Is there enough evidence at

=α0.01

to support his claim? Assume that the variable is normally distributed. Use the

-value method with tables.

hello there are five parts to the question it asks to state the hypothessis and identify the claim it asks to compute the test value find the p value and choose the null hypothesis

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
