2. The demand for hand sanitizers is off the charts due to this corona virus outbreak. People are in desperate need of hand sanitizers. Therefore, FMCGS like Unilever Bangladesh Limited is producing this life essential product in a bulk amount to help the citizens across Bangladesh to maintain the hygiene standards. Sales figures and profits for the stores are given in the following table: Unit Sales Profit (Taka) X Y 12 1000 13 1550 14 1600 15 1800 17 1900 18 2200 21 2700 25 3500

Give an example of a scatter plot with 5 points that has a correlation of r=0 on the axes below. How did you arrive at your scatter plot?
A random sample of college students was surveyed about how they spend their time each week. The scatterplot below displays the relationship between the number of hours each student typically works per week at a part- or full-time job and the number of hours of television each student typically watches per week. The correlation between these variables is r = –0.63, and the equation we would use to predict hours spent watching TV based on hours spent working is as follows: Predicted hours spent watching TV = 17.21 – 0.23(hours spent working) Since we are using hours spent working to help us predict hours spent watching TV, we’d call hours spent working a(n) __________________ variable and hours spent watching TV a(n) __________________ variable. The correlation coefficient, along with what we see in the scatterplot, tells us that the relationship between the variables has a direction that is _________________ and a strength that is ______________________. According to…
A researcher was interested in the relationship between number of close friends and self-esteem. A sample of 40 participants were recruited and asked to report the number of close friends they had, as well as their level of self-esteem. The data showed a positive correlation, such that having more close friends was associated with having higher self-esteem, r(38) = .45. Here are the descriptive statistics for the two variables: Close Friends Self-Esteem Mean 8.90 5.20 SD 3.75 2.15 In a regression equation predicting self-esteem, what is the value of b?A) 0.258B) 0.263C) 0.785D) 0.573 In a regression equation predicting self-esteem, what is the value of a?A) -1.787B) 7.496C) 2.904D) 4.818 One participant named Jesse reported that they had 4 close friends. Based on the regression equation, what would Jesse’s predicted self-esteem score be?A) 3.936B) 1.353C) 7.958D) 8.528 If Jesse’s actual self-esteem score was 5, what is the residual score?A) -2.958B) 3.647C) -3.528D)…
A researcher wanted to know the relationship between sales per 24h in a department store, the amount of rain that day (in mm) and the mean age of 1000 customers. The SPSS output is presented below. What is the correct way to report the correlation between sales per 24h and rainfall that day in APA style? Question 24 options: r(16) = -.909, p<.001 r(18) = -.909, p=.000 r(18) = -.909, p<.001 r(16) = -.909, p=.000
A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.759 b=37.685 r2=0.674041 r=-0.821 Assume the correlation is significant, and use this to predict the number of situps a person who watches 11 hours of TV can do (to one decimal place)
A study was conducted to determine if the number of hours of sleep per night was related to exam performance on an exam taken the following day. The correlation coefficient was found to be .78. Which statement is FALSE? The relationship between hours of sleep and exam performance the following day is strong. As the number of hours of sleep increases, exam performance is also expected to increase at a similar rate. The r-value is .78. The number of hours of sleep cannot be used to estimate or predict possible performance on an exam the following day.
The correlation coefficient betweem anxiaty and exam scorea of the students is -0.6 .so what is the percentage of the change in exam scores explained by anxiaty?
What does the square of the linear correlation coefficient measure (rxr)?
