Explanation Given Information: Given expression: ( 2 a 5 b 3 ) 4 − 16 a 20 b 7 . Calculation: According to given question, the expression is ( 2 a 5 b 3 ) 4 − 16 a 20 b 7 . We know that, exponential power of number means multiplying the number by itself the number of times the power is given. Also, expansion of exponential power in a bracket is done equally to each variables and the power of bracket is multiplied to power of variable. So, we have, ⇒ ( 2 a 5 b 3 ) 4 − 16 a 20 b 7 [ Using ( p . q ) r = p r . q r ] = ( 2 ) 4 × ( a 5 ) 4 × ( b 3 ) 4 − 16 a 20 b 7 [ Using ( x y ) z = x y . z ] = 16 × a 5 × 4 × b 3 × 4 − 16 a 20 b 7 = 16

The table below shows the estimated effects for a logistic regression model with squamous cell esophageal cancer (Y = 1, yes; Y = 0, no) as the response. Smoking status (S) equals 1 for at least one pack per day and 0 otherwise, alcohol consumption (A) equals the average number of alcohoic drinks consumed per day, and race (R) equals 1 for blacks and 0 for whites. Variable Effect (β) P-value Intercept -7.00 <0.01 Alcohol use 0.10 0.03 Smoking 1.20 <0.01 Race 0.30 0.02 Race × smoking 0.20 0.04 Write-out the prediction equation (i.e., the logistic regression model) when R = 0 and again when R = 1. Find the fitted Y S conditional odds ratio in each case. Next, write-out the logistic regression model when S = 0 and again when S = 1. Find the fitted Y R conditional odds ratio in each case.

The chi-squared goodness-of-fit test can be used to test if data comes from a specific continuous distribution by binning the data to make it categorical. Using the OpenIntro Statistics county_complete dataset, test the hypothesis that the persons_per_household 2019 values come from a normal distribution with mean and standard deviation equal to that variable's mean and standard deviation. Use signficance level a = 0.01. In your solution you should 1. Formulate the hypotheses 2.
