WILL UPVOTE, just pls help me answer the following questions in the attached image. Pls show complete solutions and explain them. Thank you!

Consider the multiple regression model to investigate the relationship
between the number of fishes (Y) per section of the stream and the following
independent variables: dissolved oxygen (3 < oxy < 10, in mg/liter),
maximum depth (1 < maxdepth < 8, in feet), and water temperature (5<
temp < 20, in OC). The location of the stream was also considered (lowland
and upland). 7
= 23.09 +0.199*oxy + 0.3361*maxdepth +8.6730*temp + 3.8290* lowland.
Which of the following is(are) TRUE about the estimated regression coefficient for location of the
stream?
I.
II.
The location of the stream is a categorical variable, so it is represented by a dummy variable with
upland stream as the reference variable.
Holding other factors constant, the number of fishes in lowland is 3.8290 higher than upland
streams.
A. I only
B. II only
C. Both I and II
D. Neither I nor II

Definition Definition Statistical method that estimates the relationship between a dependent variable and one or more independent variables. In regression analysis, dependent variables are called outcome variables and independent variables are called predictors.

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.
