Hi How do u solve for (b) For large U.S. companies, what percentage of their total income comes from foreign sales? A random sample of technology companies (IBM,Hewlett-Packard, Intel, and others) gave the following information.tTechnology companies, % foreign revenue: X1; n1 = 1662.855.747.059.655.341.065.151.153.450.848.544.649.461.239.341.8Another independent random sample of basic consumer product companies (Goodyear, Sarah Lee, H.J. Heinz, Toys 'R' Us) gave the followinginformation.Basic consumer product companies,% foreign revenue: x2; n2 = 1728.030.534.250.311.128.840.044.940.760.123.121.342.818.036.928.032.5Assume that the distributions of percentage foreign revenue are mound-shaped and symmetric for these two company types.(a) Use a calculator with mean and standard deviation keys to calculate x1, S1, x2, and s2. (Round your answers to two decimal places.)X1 = 51.66%S1 = 7.92%X2 = 33.6%S2 = 12.25%(b) Let 41 be the populationean for x1 and let µz be the population mean for x2. Find a 95% confidence interval for H1 - 42. (Roundmanswers to two decimal places.)lower limit10.68X %upper limit25.43X %
