The community hospital is studying its distribution of patients. A random sample of 317 patients presently in the hospital gave the following information: Type of Patient Old rate of occurrences of the types of patients Present number of occurrences of these types of patients Maternity ward 20% 65 Cardiac ward 32% 100 Burn ward 10% 29 Children's ward 15% 48 All other wards 23% 75 Using a 5% level of significance, test the claim that the distribution of patients in these wards has not changed.

Do you think new package labeling or doing nothing is best? You will want to calculate the percent of bars produced that are within 5 grams of 1000 grams and the percent of bars produced that are within 5 grams of 990 grams. In other words, given a uniform distribution between 980 and 1000, what is the probability of being between 995 and 1005 and what is the probability of being between 985 and 995?
Studies have shown that the percent of California Community College students that take a certain number of units per quarter follow the following distribution.

A researcher has run an experiment on the effects of early cognitive simulation on children and their school success at age 10 years. He wants to compare his sample results to the normal distribution (z-distribution), but he is not sure whether the population distribution is normal or not. He comes to you as an expert in statistics for advice. Can he do this? Why or why not? What conditions must be met?
In a certain populalion, let us assume that IQ scores are normally distributed with mean of 100 and standard devialion of 15. What percentage of the population have IQ scares more than 116? Select one: a. 0.6808 O b. 0.2327 O c. 0.3192 C d. 0.8577 e. 0.1423 f. 0.7673
