- A study of 25 online jewelry retailers was done to find the statistical relationship between the price y in dollars of a diamond ring and the weight x in carats of the diamond. Based on this data the following least-squares regression line was found: ^y=−6047.75+11975.14x What is the predicted price of diamond ring a 2.2 carat diamond using this regression line. Round your answer to two decimal places.A paper† gave data on x = change in Body Mass Index (BMI in kilograms/meter2) and y = change in a measure of depression for patients suffering from depression who participated in a pulmonary rehabilitation program. JMP output for these data is shown below. A scatterplot titled "Bivariate Fit of Depression Score Schange by BMI Change" has 12 points and a line plotted on it. The horizontal axis is labeled "BMI change" and ranges from about −0.8 to about 1.8. The vertical axis is labeled "Depression score change" and ranges from about −2 to 20. The points are plotted from left to right in an upward, diagonal direction starting from the middle left of the diagram. The points are very scattered and are between approximately −0.5 to 1.5 on the horizontal axis and between approximately −1 to 18 on the vertical axis. A line with positive slope titled "Linear Fit" is drawn across the plot to approximate the trend of the points. The line enters the viewing window at about (−0.8, 3) and exits at…Researchers found a positive assodation between the students' performance in STAT 1000 and their first-year cumulative college GPA.

- 4. A man claims to be able to distinguish between two kinds of wine with 90% accuracy and presents his claim to an agency interested in promoting the consumption of one of two kinds of wine. The following experiment is conducted to check his claim. The man is to taste the two types of wine and distinguish between them. This is to be done nine times with a 3-minute break after each taste. Assume that each tasting is independent. It is agreed that if the man is correct at least six out of the nine times, he will be hired. (a) Assume that the man is guessing. What is the likelihood of the man being hired? (b) Assume now that the man's claim is true (i.e. that his probability of success in each tasting is 0.9). What is the chance of the man being hired?Hello, I am working on an assignment in research design.

This equation has an R² value of 0.305162, and the coefficient of BARS, has a value of 0,088136. Which of the following conclusions is valid? Answer Keypad Keyboard Shortcuts m Tables O If there is no cigarette tax in a city that allows smoking in bars, the approximate number of cigarette packs sold per 1000 people is 58803. O According to the regression equation, cities that allow smoking in bars have lower cigarette sales than cities that do not allow smoking in bars. O More than half of the variation in cigarette sales is explained by cigarette taxes and whether or not a city allows smoking in bars.…Suppose we run the following OLS regression JobStr B1 + B2 M + B3 Exp+ B4 Edu + u %3D to explain an individual's job stress level by their gender (M for male dummy), work experience (Exp) and education (Edu), using a sample of 300 observations.
