A company has tool cribs where workmen draw parts. Two men have applied for the position of distributing parts to the workmen. George Fuller is fresh out of trade school and expects a $6 per hour salary. His average service time is 4 minutes. John Cox is a veteran who expects $12 per hour. His average service time is 2 minutes. A workman's time is figured at $10 per hour. Workmen arrive to draw parts at an average rate of 12 per hour.

a. What is the average waiting time a workman would spend in the system under each applicant?

The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

Step 1 of 6:

Find the estimated slope. Round your answer to three decimal places.

Step 2 of 6:

Find the estimated y-intercept. Round your answer to three decimal places.

Step 3 of 6:

Determine if the statement "All points predicted by the linear model fall on the same line" is true or false.

Step 4 of 6:

Find the estimated value of y when x=3.5x=3.5. Round your answer to three decimal places.

Step 5 of 6:

Substitute the values you found in steps 1 and 2 into the equation for the regression line to find the estimated linear model. According to this model, if the value of the independent variable is increased by one unit, then find the change in the dependent variable yˆy^.yˆ

Step 6 of 6:

Find the value of the coefficient of determination. Round your answer to three decimal places

Assignment #6: Testing Correlations Directions: Use the Bivatiate Correlation function and the Options submenu to answer each of the questions based on the above scenario. The superintendent has continued the examination of data by examining the relationship between attendance rate and percent of students eligible for free or reduced priced lunch. The district data used for the analysis are contained below.

School 1 2 3 4 5 6 7 8 9 10 11  % Free or Reduced 70.4 49.4 58.9 65.1 50.5 58.9 32.7 55.8 59.7 65.4 53.8  Attendance Rate  93.3 93.7 95.6 93.6 94.6 94.6 95.7 92.3 94.3 91.8 95.3

1. What is the mean percent of students receiving free or reduced lunch? What is the mean attendance rate? 2. What are the standard deviations for the percent of students receiving free or reduced lunch and attendance rate? 3. State an appropriate null hypothesis for this analysis. 4. What is the value of the correlation coefficient? 5. Based on the value of the correlation coefficient, how would you classify the strength of this relationship? 6. Based on the information from the scenario, what is the appropriate value for the degrees of freedom? 7. What is the reported level of significance? 8. Present the results as they might appear in an article.

1. Blood Pressures. Among human females, systolic blood pressure (measured in mmHg) is normally distributed, with a mean of and a standard deviation of 06.3, μ = 1 .9. σ = 8 a. Connie’s blood pressure is 117.4 mmHg. Calculate the z-score for her blood pressure.

b. Mark Connie’s x-value and z-score (as well as the mean) in the correct locations on the graph. c. Interpret the meaning of Connie’s z-score value. 2. Finding raw values from z-scores. California condors are among the largest birds in North America, with wingspans of around 10 feet. Among the California condor population, let’s suppose that wingspans are normally distributed, with a mean of 106 inches, and a standard deviation of 5 inches. The California condor pictured has a wingspan corresponding to a z-score of -0.6. Determine the condor’s actual wingspan in inches; show your work. Place the z-score and x-value for the condor’s wingspan on the graph, along with the mean.

3. Using z-Scores to Compare Data from Different Distributions. Before applying to law school in the US students need to take the LSAT. Before applying to medical school, students need to take the MCAT. Here are some summaries for each (both are normally distributed): the Mean Standard deviation LSAT 51 μ = 1 0 σ = 1 MCAT 5.1 μ = 2 .4 σ = 6 Juwan took both. He scored 172 on the LSAT and 37 on the MCAT. On which the did he do relatively better compared to other test takers? Justify your answer below; show your work and explain your reasoning.
