Draw and label (with ?, ?) a standard normal curve

Draw a graph

Weights of incoming college freshmen are normally distributed with a mean of 150 lbs. and a standard deviation of 25 pounds. What z-score and what weight represents the first quartile for incoming freshmen?

About what percentage of a normal distribution falls within 2.5 standard deviations of the mean?

How does the normal curve allow behavioral scientists to compare different types of scales, tests and instruments. Using Z scores

Response time is an important statistic for measuring the effectiveness of a fire department, and is measured as the difference between the time a fire station receives a call and the time the first piece of fire equipment leaves the station. The response times for fire departments in a large city are found to have an approximately Normal distribution, with a mean of 4.5 minutes and a standard deviation of 1.2 minutes. What percentage of fire station response times are under 3 minutes?

What is normal distribution?

A deviation score of 0.00 indicates that the individual

est scores followed a near-normal distribution of ????? ~ ?(47, 2). What percentage of scores are more than 1 standard deviation away from the mean? Is it higher or lower than expected? What percentage of scores are more than 2 standard deviations away from the mean? Is it higher or lower than expected?

I. Mean=Median=Mode II. Area under the curve= 100%, mean=0 III. there are a family of standard normal curves Which is true of the standard normal curve? A) I only B) II only C) I and II D) I, II, and III
