Using this example, what is the odd ratio representing the odds of being infected with Covid for a person living in a single home with multiple families compared to a person living in a single home with a single family with multiple generations? Enter the answer up to three digits after decimal **Analysis of Living Situations and COVID-19 Log-Odds**In a study modeling the likelihood of contracting COVID-19 based on living situations, several indicator variables were defined:- **Z1**: Resided in an apartment building with a single nuclear family (e.g., parents and children).- **Z2**: Resided in an apartment building with a single family including multiple generations (more than 2 generations).- **Z3**: Lived in a single-family home or townhouse with multiple families.- **Z4**: Lived in a single-family home or townhouse with a single family including multiple generations (more than 2 generations).The **reference category** for comparison was defined as living in a single-family home or townhouse with a single nuclear family.The **fitted logistic regression equation** derived from the study is:\[ \text{logit} = 0.20 + 0.10*Z1 + 0.30*Z2 + 0.45*Z3 + 0.20*Z4 \]This equation helps to understand how different living conditions may influence the probability, expressed in log-odds, of contracting COVID-19.

Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couples in their midtwenties who were married or had been dating for at least two years. They zapped the man's hand with an electrode while the woman watched, and measured the activity in several parts of the woman's brain that would respond to her own pain. Brain activity was recorded as a fraction of the activity observed when the woman herself was zapped with the electrode. The women also completed a psychological test that measures empathy.

Is the average time to complete an obstacle course shorter when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye.

What would happen to the variance of test scores if an instructor multiplies each score by 2? a. It increases by 2 points b. it becomes four times as large c. It stays the same d. it will decrease
A population of scores with p = 38 and CT = 6 is standardized to create a new population with p = 50 and CT =10. What is the new value for each of the following scores from the original population? original score X = 26 X = 35 X = 44 X = 47
In a population of scores, x=45 corresponds to z=+2.00 and x=30 corresponds to z=-1.00 what is the population mean
The time it takes an employee to package the components of a certain product is normally distributed with ? = 7.5 and ? = 1.5 minutes. As an incentive, management has decided to give a bonus to the 25% of employees who took the shortest amount of time to package the components. Find the amount of time taken to package the components that will indicate that an employee should get a bonus. (Round your answer to two decimal places.) An employee must package components in a time minutes.
A scale is known to be "low-calibrated" in that it measures an aluminum bar to be 4 grams lower than the actual weight. If ????μold is the mean of all possible measurements of the bar using the old calibration, and ????μnew is the mean of all possible measurements of the bar using a re-calibrated scale. It is desired that ????−????=4μnew−μold=4. Consider the test ?0:????−????=4H0:μnew−μold=4 vs. ?0:????−????≠4H0:μnew−μold≠4 Sample after calibration: mean is 95.8 , SD is 4.9 and sample size is 10 Sample before calibration: mean is 89.352 , SD is 4.2 and sample size is 62 We do not know population standard deviations. What is the p-value? (Hint: best to use software, or else the Desmos Calculator for the 2 sample T and Z test)
