Using the graph on the image provided, what would be the answer for the question number 4 below?4) Imagine you are studying the effect of teaching online on job satisfaction in college professors. Are these data useful for your research purposes? Why or why not? **Practice: Correlations****Faculty job satisfaction while teaching online**A scatterplot graph shows the relationship between the number of online classes taught (X-axis) and faculty job satisfaction (Y-axis). The X-axis is labeled from 0 to 8 for the number of classes, while the Y-axis ranges from 0 to 8 for job satisfaction. The scatterplot depicts a downward trend, indicating a negative correlation between the number of classes and job satisfaction. A dotted line represents the best fit, sloping downward.You collect data on college professors to assess whether there is a correlation between their self-reported job satisfaction (Y) and the number of courses they teach online (X). You find that these data are correlated at \( r = -0.31, p < 0.05 \). Please use this scatterplot to answer the following questions:1) Based on these data, can you use the number of online courses to predict levels of job satisfaction? Why or why not?2) Please describe the nature of this correlation, conceptually. How would you describe this relationship to a friend who does not know what a “correlation” means?3) Using these data, you conclude that teaching online causes faculty job satisfaction to decrease? Why or why not?4) Imagine you are studying the effect of teaching online on job satisfaction in college professors. Are these data useful for your research purposes? Why or why not?---*More exercises await you on the second page. Keep scrolling…*

subject: Quantitative Analysis For Business Please answer both. Use the image for question 10. 10. A hair stylist used market research to learn that members of different age groups have different preferences for positive and negative advertisements. Research participants could mark their preference for only one of the two ads. The positive ad presented a model with attractive hair supported by a message affirming the decision to schedule hair styling services, whereas the negative ad displayed a model with unattractive hair supported by a message describing the need for hair styling services. Results are shown in the table below: What is the probability of a site visitor either preferring negative ads or being a member of age category B? 6% 62% 56% 68% 93% 11. A hair stylist averaged 21 clients per day over the past several months. Typically four of these clients have been male. What is the probability for the total number of female clients the hair stylist can expect…

Scenario: Album Sales: A study was done to see whether getting radio airtime and spending money on advertisements accurately predicts the number of album copies sold. A random sample of 200 artists’ albums were tracked on the number of times their songs play on the central radio station, how much money (in thousands) they spent on advertisements, as well as the number (in thousands) of album copies were sold. A record company wanted to determine if there was a positive relationship between album sales and the other two variables (money spent on advertisements and number of albums sold) What is the Null and alternative hypotheses (based on context of study) in symbols and words:
PART I: For this part, we will divide the data set into two groups: those who have infection and those who do not. Consider only those who have an infection.1. For these subjects only, construct a stemplot for the variable “heart rate”. (We will be making this into a back-to-back stemplot later, so leave room on the left side.)2. Discuss the shape of your stemplot. Is it symmetric? Positively skewed? Negatively skewed? None of these? Are there any outliers?3. How would you describe the center and the spread of this distribution?4. Find the five-number summary.5. Construct a box plot.
