One environmental group did a study of recycling habits in a California community. It found that 73% of the aluminum cans sold in the area were recycled. (Round your answers to four decimal places.)
a) If 388 cans are sold today, what is the probability that 300 or more will be recycled?
b) Of the 388 cans sold, what is the probability that between 260 and 300 will be recycled?
Suppose the manufacturers claim is right, determine the probability the mean of sample is 47,840 miles or less?
Do the data demonstrate that the true mean photometer reading for the color density is significantly different from 12 at 3 percent level of significance?
Random sample of 64 services is selected. Assume the population consists of 400 services. Find out the standard error of mean.
Such things as historical documents, newspaper reports, TV and radio broadcasts, when used in research, represents
Using symbols mention null hypothesis and alternative hypothesis.
Use the population standard deviation along with the sample mean, S, and find a 92% confidence interval for the population mean. Is the true population mean contained in this interval?
Continuous random variable is uniformly distributed between a and b. The probability density function between a and b is.
What does the coefficient of determination tell you about the variation in attendance and the variation in the number of exhibitors?
Random sample of 100 people yielded following data on number of tissues utilized in a cold: x-bar = 38, s = 20. By using sample information provided, compute the value of test statistic for the relevant hypothesis test.
Test whether the mean rate is less than 6%. Use P-value approach.
Note that under the exponential assumption, P(X>t) = exp(-t/theta). If t=5, use the result from (a) to find an approximate one-sided lower 95% confidence limit for theta.
Test whether there is a statistical difference between the two proportions at the 5% significance level.
