solution with normal curve 300 qualified voters sampled in a certain city are asked if they favor an additional 5% sin tax toprovide the badly needed revenues for the city projects. If more than 220 but fewer than 260 favorthe sin tax, we therefore shall conclude that 60% of the voters are for it.(a) Find the proba. of committing a type I error if 60% of the resident voters favor the increased tax.(b) What is the probability of committing a type Il error using this test procedure if actually only 48%of the resident voters are in favor of the additional tax?

Probability that a voter wil favor that it is a sin tax is:Sample size: It is given that more than…

Answered: 300 qualified voters sampled in a…

Part 2: Regression Based on the correlation you ran to assess the relationship between # of exposures and perceived connection strength recalled, please carry out the steps to determine the equation for the regression line (or best-fitting line) а. Step 1: find the slope and y-intercept b. Step 2: Using these values, write the equation for the best fitting line, but make sure to write it in terms of the specific predictor (X) and predicted (Y) variables of interest. In other words, your equation should use variable names “# of exposures" and "perceived strength of connection rating", rather than X and Y. Using the regression equation, please predict the perceived connection strength score for a student exposed subliminally to the stranger's face seven times. Make sure to show your work с. d. Using the regression equation, draw the line of best fit on your scatterplot. Please use at least 3 points to anchor your line and show your work.
ariants/1017828/take/5/ At the beginning of the COVID-19 Pandemic, the Department of Health used a graph to represent the prediction of the number of active cases, if no interventions were made. The vertical axis gives the num- ber of active cases and the horizontal axis shows the number of days since the start of the pandemic. Pennsylvania residents were asked to quarantine to flatten the curve of the graph that represented the number of active infections. Which of the following statements are true? Select all that apply. A B Flattening the curve would represented a vertical compression of the graph of the data. Flattening the curve would be a horizontal stretch of the graph of the data.

Due in 3 hours, 41 minutes. Due Sat 04/18/2020 11:59 pm Show Intro/Instructions A regression was run to determine if there is a relationship between hours of study per week (x) and the final exam scores (y). The results of the regression were: у-ах+b a=6.704 b=30.59 p2=0.972196 r=0.986 Use this to predict the final exam score of a student who studies 8.5 hours per week, and please round your answer to a whole number.

Using the regression model, which is the estimated score in quiz of a student and is the number of hours the student spent in studying before the quiz, interpret the regression constant (bo) 50. None of the above. O The estimated score of a student who had 0 hours spent in studying is 50. The regression constant is not appropriate to interpret. The number of hours needed to have a score of 100 is 50.
