Hello I need help with problem f thank you!

9. The data shown below reflects the age of a man and a woman at the time of their wedding. The linear regression equation for this data is Couples a. Alessandra & Aaron David & Daniella Gloria & Gabriel Mohammed & Mariam Raphael & Rebecca Samantha & Steven y = -1.799 + 1.077x Woman's Age 24 26 29 31 50 33 Man's Age 23 28 33 31 53 29 Plot the observations in a scatterplot. Make sure to label the axes with Man's Age being the response variable and Woman's Age being the explanatory variable. b. Describe the possible association (trend, strength, and shape) in context. c. Calculate the correlation coefficient. d. What is the expected age of a woman when her husband is 28 years old at the time of marriage? Round to the nearest whole number. e. Interpret the slope of the linear regression line in the context of the data. f. Interpret the y-intercept of the linear regression line in the context of the data. Then, state whether that value is meaningful.
