A group of researchers were studying the weight of young girls from ages 10-14 and then created a model to explain the relationship of weight and age: Weight = B0 + B1*Age + E 1) In the following model, what does B0 represent? Weight = B0 + B1*Age + E Group of answer choices 2) In the following model, interpret B1 if B1 equals 7 pounds? Weight = B0 + B1*Age + E Choose the best, most complete answer. We...

The CDC estimates that 20% of people in the US between the ages of 15 and 24 have an STI. Suppose we do a test at a local college campus and find that 11 out of 117 people tested have an STI. Is this random variation or does this school have a lower than average level of infection? What test should we perform and why? What is your null and alternative hypothesis? Perform the test. What is the test statistic...

The marital status distribution of the U.S. male population, ages 15 and older, is as follows:...
The marital status distribution of the U.S. male population, ages 15 and older, is as follows: 31.3% never married, 56.1% married, 2.5% widowed, and 10.1% divorced/separated. A random sample of 400 U.S. young adult males, 18 to 24 years old, found 140 never married, 238 married, 2 widowed, and 20 divorced/separated. Using α = 0.10, is this evidence that males in this age group follow a different distribution than all males in the U.S.? Write the hypotheses, calculate the expected...
