(COMPUTE AND INTERPRET CONFIDENCE INTERVAL ESTIMATES) . According to the U.S. Census Bureau, 43% of men who worked at home were college graduates. In a sample of 500 women who worked at home, 162 were college graduates. Construct a 98% confidence interval for the proportion of women who work at home who are college graduates. Find the critical values, find E , the margin of error, then compute a nd interpret your interval estimate with a full sentence. Critical value:...
SupposeZ∼N(0, 1). Use R to find:(a) What percent of the area under the density curve is within±one standard devi-ation of the mean (i.e.,P(μ−σ < Z < μ+σ))?(b) What percent of the area under the density curve is within±2σof the mean?(c) What percent of the area under the density curve is within±3σof the mean?(d) Are these percentages the same forX∼N(μ=−15,σ2= 50)?

Surface Area - Surfaces of Revolution In Exercises 43–70, a curve C with parametrization = X(t), y=0, z = 2(t), for t in (a, b), is revolved about the z-axis to create a surface S. Find the surface area A of S. NOTE: Only the first four prob- lems are like Example 13.2.7 (a) and you will have to use integrals over two subintervals of [a, b] to compute A. 13. X = t3 – įt,...
Question 14 < If n=15, 2(x-bar)=43, and s=4, find the margin of error at a 99% confidence level Give your answer to two decimal places.
Find the area of the right half of the cardioid: r = 4+3 sin 0. Find the area enclosed within one loop of the curve: r = 4 cos 30.
for the function f(x)=cos(x) define within [0, pi], what will be the maximum error if f is approximated by 10th and 15th degree interpolating polynomials. Solve this in MatLab
For n=47 and X=43, find the exact proportions p and q. = 0 :

Question ID Normal Curve From the normal curve, we know that there are 68% of the data are within one standard deviation(which is between -1o and +1a 95% are within two standard deviation (between -Zo and x + 2σ) and 99.5% are within three standard deviation(between f-3ơ and f+3c). From the figure on the left, we also notice that there are 34% of the data are between and f+10. And there are .15% of the data are above x+3o,...
