The human resources department of a consulting firm gives a standard creativity test to a randomly selected group of new hires every year. This year, 85 new hires took the test and scored a mean of 113.1 points with a standard deviation of 16.4. Last year, 60 new hires took the test and scored a mean of 116.9 points with a standard deviation of 18. Assume that the population standard deviations of the test scores of all new hires in the current year and the test scores of all new hires last year can be estimated by the sample standard deviations, as the samples used were quite large. Construct a 90% confidence interval for H1-H2, the difference between the mean test score u, of new hires from the current vear and the mean test score u, of new hires from last year. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of formulas.) Lower limit: || Upper limit:

A health psychologist is interested in the potential effect that a change in career focus can have on cardiovascular disease for those in high stress jobs. She chooses to study divorce lawyers (a population that averages a mean systolic blood pressure of 142 with a standard deviation of 13) and measures the blood pressure of 23 former divorce lawyers who switched to environmental law. Those 23 lawyers have a mean systolic blood pressure of 131. If all divorce lawyers switched to environmental law, what would you expect the mean systolic blood pressure to be with 99% confidence? What is the highest estimated value for the mean systolic blood pressure for divorce lawyers who switch to environmental law?
Two friends, Karen and Jodi, work different shifts for the same ambulance service. They wonder if the different shifts average different numbers of calls. Looking at past records, Karen determines from a random sample of 40 shifts that she had a mean of 4.8 calls per shift. She knows that the population standard deviation for her shift is 1.4 calls. Jodi calculates from a random sample of 31 shifts that her mean was 5.6 calls per shift. She knows that the population standard deviation for her shift is 1.2 calls. Test the claim that there is a difference between the mean numbers of calls for the two shifts at the 0.05 level of significance. Let Karen's shifts be Population 1 and let Jodi's shifts be Population 2. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
A random sample of 100 chemistry students were asked how many lab classes he or she was enrolled in September 2000. The results showed a mean of 1.65 lab classes with a standard deviation of 1.39. Ten years later, a similar survey was conducted to determine if the distribution changed. The 2010 sample mean was 1.82 with a standard deviation of 1.51. Do the data provide statistical evidence that the mean number of lab classes taken in the first survey is different from the survey taken 10 years later? Perform the appropriate test using a = 0.02.
Data were collected on the top 1,000 financial advisers. Company A had 239 people on the list and another company, Company B, had 121 people on the list. A sample of 16 of the advisers from Company A and 10 of the advisers from Company B showed that the advisers managed many very large accounts with a large variance in the total amount of funds managed. The standard deviation of You may need to use the appropriate technology to answer this question. the amount managed by advisers from Company A was s, at a = 0.10 to determine if there is a significant difference in the population variances for the amounts managed by the two companies. What is your conclusion about the variability in the amount of $589 million. The standard deviation of the amount managed by advisers from Company B was s, = $486 million.

Two friends, Karen and Jodi, work different shifts for the same ambulance service. They wonder if the different shifts average different numbers of calls. Looking at past records, Karen determines from a random sample of 41 shifts that she had a mean of 5.1 calls per shift. She knows that the population standard deviation for her shift is 1.5 calls. Jodi calculates from a random sample of 32 shifts that her mean was 5.8 calls per shift. She knows that the population standard deviation for her shift is 1.2 calls. Test the claim that there is a difference between the mean numbers of calls for the two shifts at the 0.01 level of significance. Let Karen's shifts be Population 1 and let Jodi's shifts be Population 2. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
For a study conducted by the research department of a pharmaceutical company, 245 randomly selected individuals were asked to report the amount of money they spend annually on prescription allergy relief medication. The sample mean was found to be $17.80 with a standard deviation of $4.30. A random sample of 225 individuals was selected independently of the first sample. These individuals reported their annual spending on non-prescription allergy relief medication. The mean of the second sample was found to be $18.20 with a standard deviation of $3.60. As the sample sizes were quite large, it was assumed that the respective population standard deviations of the spending for prescription and non-prescription allergy relief medication could be estimated as the respective sample standard deviation values given above. Construct a 90% confidence interval for the difference H₁ H₂ between the mean spending on prescription allergy relief medication (₁) and the mean spending on non-prescription…
The City of Calgary reports that the number of vehicles that use the Crowchild Trail bridge various on weekdays. This variation can be modeled by the Normal distribution with a mean of 107500 vehicles and a standard deviation of 8800 vehicles per day. You pick a weekday at random and set out a traffic counter on both the north-bound and south-bound lanes of the Crowchild Trail bridge. At the end of a 24-hour period, you are to download the data from the traffic counter and add the two figures to represent the total vehicle usage,X. (a) What is the probability that the total vehicle usage figure will be more than 120500 vehicles? P(X≥120500)= (b) What is the probability that the total vehicle usage figure will be between 80000 and 101000? P(80000≤X≤101000)= (c) Find the 91 percentile. That is, 91% of the time, the total number of vehicles that use the Crowchild Trail bridge in a 24-hour weekday period is at most how many?

A Statistics instructor wanted to compare the scores on the same final exam given to students at a local community college and local university. The Statistics instructor feels that students at the community college would be better prepared and have higher exam scores on the final exam. After grading the final exams from both institutions, the Statistics instructor found that for a sample of 36 community college students, the sample had a mean score of 84 with a standard deviation of 3.4. A sample of 45 university students had a mean score 79 with a standard deviation of 2.6. Construct a 95% confidence interval for the difference between population mean exam scores. Round your final results to one decimal place. _____________ ≤ ??? − ????? ≤ ______________

Looking at past records, Karen determines from a random sample of 39 shifts that she had a mean of 4.7 calls per shift. She knows that the population standard deviation for her shift is 1.5 calls. Jodi calculates from a random sample of 31 shifts that her mean was 5.4 calls per shift. She knows that the population standard deviation for her shift is 1.2 calls. Test the claim that there is a difference between the mean numbers of calls for the two shifts at the 0.02 level of significance.
