Suppose the number of beds filled per day in a mediumsized hospital is normally distributed. A hospital administrator tells the board of directors that, on the average, at least 184 beds are filled on any given day. One of the board members believes that the average is less than 184 and she sets out to test to determine if she is correct. She secures a random sample of 16 days of data (shown below). Use α = 0.05 and the sample data to test the board member’s theory. Assume the number of filled beds per day is normally distributed in the population.

Number of Beds Occupied per Day
173 149 166 179
189 171 152 194
177 169 188 160
199 175 172 187

A medical investigation claims that the average number of contaminations per week at the Main Hospital is 19.2. A random sample of 10 weeks had a mean number of 20.5. The sample standard deviation is 3.5. Is there enough evidence to reject the investigator’s claim at alpha =.05? Steps to be covered: state the hypothesis and identify the claim find the critical value from the table and mention the acceptance range compute the test value (t test) make the decision...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 22 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d=(blood pressure before taking new drug)−(blood pressure after taking new drug)d=(blood pressure before taking new drug)−(blood pressure after taking new drug). Use a significance level of α=0.1 for the...

At a large hospital average number of new acquired infection is normally distributed with u=17.5 and standard deviation of 2.5. After the new procedure were implemented, an SRS of 36 weeks found a mean 15 infection per week. At 5% level of significance (a=0.05), is this evidence that the mean infection is different from 17.5 infections per week. a. state the hypotheses b. calculate the value of the test statistic. c. determine the p-value d. state your conclusion in terms...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d=(blood pressure before taking new drug)−(blood pressure after taking new drug). Use a significance level of α=0.05 for the test. Assume that the systolic blood pressure levels are normally...

A sociologist studied gender differences in the average number of hours worked per day among employees at a law firm (there are 42 men and 19 women employed at this firm). She obtained the following results: men work, on average, 52 hour per week and women work, on average, 56 hour per week. The standard deviation for men is 12 hours and the standard deviation for women is 9 hours. Test the null hypothesis of no difference in the average...

3) The director of a medical hospital feels that her surgeons perform fewer operations per year than the national average of 211. She selected a random sample of 15 surgeons and found that the mean number of operations they performed was 208.8. The standard deviation of the sample was 3.8. Is there enough evidence to support the director’s feelings at α = 0.10? Assume the variable is normally distributed. a) State the appropriate null and alternate hypotheses. b) Compute the...
