Assume that heights of women are normally distributed with a mean given by 63.6 in. and a standard deviation given by 2.5 in. (based on data from the National Health Survey). The Beanstalk Club, a social organization for tall people, has a requirement that women must be at least 70 in. (or 5 ft 10 in.) tall. What percentage of women meet that requirement?

Find the z-score for the given shaded region under the standard normal distribution. Round your answer to two decimal places. Shaded Area - 0.82 -2. Z-Score =

On a Normal curve what z-score marks the 16th percentile?  Put your answer rounded to 2 decimal places if needed  On your paper, hand sketch the standard normal curve, mark the horizontal axis in standard deviation units and shade the area on the normal curve that you found.

Using the standard normal distribution, find the two z-scores that that form the middle shaded region. The shaded region is symmetric about  z=0. Round your z-scores to two decimal places. Shaded Area=0.32 Negative z-score =  Positive z-score =

After a lot of work, a studio launches a new video game. The studio believes that gamers will like the game and in particular, states that the average rating,μ, that the players will grant you will be greater than 78. The mean score of a random sample of36players is82.3.Suppose the population standard deviation of the scores is known to be10.8. Is there enough evidence to support the claim that the average player rating is higher than 78? Perform a hypothesis test using the significance level of0.05. (a) Formulate the null hypothesish and the alternative hypothesish ₁. ho: D 0 h 1: (b) take a testz and find the p-value .
