The relationship between IQ level and exam score was estimated as below in a linear format. (IQ level and exam scores are both measured in points) Exam score = 1.38 * IQ level - 67.43 (The p-value for the coefficient of IQ level is 0.04.) Base on the above equation, which of the following statements are true? (Select all that apply. There can be more than one answer.) The expected exam score of a person with an IQ level of 100 points is 70.57 The expected exam score of a person with an IQ level of 0 points is 1.38 points As a person’s IQ level increases by 1 point, his or her exam score is expected to increase by 1.38

Gestation For women, pregnancy lasts about 9 months.In other species of animals, the length of time fromconception to birth varies. Is there any evidence thatthe gestation period is related to the animal’s lifespan?The first scatterplot shows Gestation Period (indays) vs. Life Expectancy (in years) for 18 speciesof mammals. The highlighted point at the far rightrepresents humans. a) For these data, r = 0.54, not a very strong relation-ship. Do you think the association would be stronger or weaker if humans were removed?Explain.b) Is there reasonable justification for removing humansfrom the data set? Explain.c) Here are the scatterplot and regression analysis for the17 nonhuman species. Comment on the strength of theassociation.d) Interpret the slope of the line.e) Some species of monkeys have a life expectancy ofabout 20 years. Estimate the expected gestation periodof one of these monkeys.
You are interested in predicting the length of someone's nose on the basis of the number of lies a person tells per day (the Pinocchio hypothesis). You collect data from 100 random individuals and find that the mean number of lies told is 12 by age 25 (age limit for sample). Mean nose length among participants is 5.2 cm (bridge to tip). Based on the data, the slope of the relationship is 0.49. What is the y-intercept? (round to two decimal places).
Answer for the following question blank spaces. The slope b1 =___________ indicates that for each increase of one hour in studying time, the predicted change in the final exam score is__________. In other words, the final exam score is predicted to increase by a mean of 3 points for each onehour increase in studying time.
The average electrician in Harris County charges $50 per hour and the standard deviation of the hourly charge for an electrician is $10. The average number of years the electricians have been in the professionis 20and the standard deviation for the hourly rate is 4. The covariance between the years of experience and hourly charge is 30. a)Construct the Regression Equation: (Hint y = a + bx) b)What do you expect an electrician with 25 years of experience charge?
