2. An article in Fortune (September 21, 1992)claimed that nearly one-half of all engineerscontinue academic studies beyond the B.S.degree, ultimately receiving either an M.S. or aPh.D. degree. Data from an article inEngineering Horizons (Spring 1990) indicatedthat 117 of 484 new engineering graduateswere planning graduate study.2.1. Are the data from Engineering Horizonsconsistent with the claim reported by Fortune?Use a=0.05 in reaching your conclusions. Findthe P-value for this test.2.2. Discuss how you could have answered thequestion by constructing a two-sidedconfidence interval on p. Find the confidenceinterval.

We want to find P-value and confidence interval

Data from the Bureau of Labor Statistics indicates that in a certain month, 35.7% of the labor force had a high school diploma or fewer years of education, 29.4% had some college or an associate's degree, and 34.9% had a bachelor's degree or more education. Of those with a high school diploma or fewer years of education, 5.5% were unemployed. Of those with some college or an associate's degree, 4.4% were unemployed, and of those with a bachelor's degree or more education, 2.4% were unemployed. Find the probability that a randomly chosen labor force participant has some college or an associate's degree given that he or she is unemployed. 12 The probability is 0 (Type an integer or decimal rounded to three decimal places as needed.)

A psychologist believed that as children get older, they engage in more “inactive activities” such as playing computer games, watching TV and surfing the internet. She collected data from 10 children. She recorded the age of each child and the amount of activity (in hours) the child engaged in per week. Age Activity 7 4.3 9 3.2 10 1 13 1.5 12 1.2 15 0.8 9 3 12 4 15 1.5 14 1.9 Using excel, obtain a scatterplot of the data. Discuss the relationship between age and activity based on the scatterplot. Using excel, obtain the simple linear regression linear regression line predicting activity from age. Interpret the intercept and slope of the regression line. By hand, predict the amount of activity for age = 14. By hand, calculate the residual for age = 14 Using excel output, test the null hypothesis that the slope coefficient is zero using the p-value approach. Write one sentence interpreting the meaning of this result. Make sure to report the test statistic…
