Q1:The percent of female wage and salary workers who are paid hourly rates is given below for the years 1979 - 1992. Year Percent of workers paid hourly rates 1979 61.2 1980 60.7 1981 61.3 1982 61.3 1983 61.8 1984 61.7 1985 61.8 1986 62.0 1987 62.7 1990 62.8 1992 62.9 1. Using "year" as the independent variable and \"percent" as the dependent variable, make a scatter plot of the data. 2. Does it appear from inspection that there is a relationship between the variables? Why or why not? 3. Calculate the least-squares line. Put the equation in the form of y= a + bx 4. Find the correlation coefcient. Is it signicant? How it helps you to proceed. 5. Write the hypothesis 6. Write Pvalue with alpha and state decision, 7. Based on the above data, is there a linear relationship between the year and the percent of female wage and salary earners who are paid hourly rates? 8. Are there any outliers in the above data? i. What is the estimated percentage for the year 2050? Does the least-squares line give an accurate estimate for that year? Explain why or why not? 9. Remove outlier from the data values and Calculate the least-squares line again. Put the equation in the form of y= a + bx 10. What is the New slope of the leastsquares (bestt) line? Interpret the slope. 11. Try to Predict y for x= 1988 by using the best t line in steps (3) and (9). Do you observe anything
