Nielson Media Research reports the household mean viewing time during the 8:00 p.m. to 11:00 p.m. time period is 7.75 hours per week. This was base on a sample size of 180 household resulting in a sample standard deviation of 3.45 hours. What is the 95% confidence interval estimate of the mean television viewing time per week during the 8:00 p.m. to 11:00 p.m. time period?
Is it reasonable to conclude that this set of n = 16 people is not a representative random sample of registered voters?
what is the required sample size is the error is to be less than 1/2 hour with a 95% level of confidence?
Assume that the process is in control and that the population of all jar fills is normally distributed.
Use this information to construct a probability table, and then calculate each of the following probabilities:
Test hypothesis that mean weight of 2 sheets are equal against alternative that they are not(suppose equal variances). Use α=0.05 and suppose equal variances. Determine the P value.
Show that someone will think that the claim has more than a fifty percent chance of being true if p > q / (1 + q). Explain.
Test whether there is a statistical difference between the two proportions at the 5% significance level.
A journal polled its readers to determine the proportion of wives who, if given a second chance, would marry their husband again.
Final step to be performed when testing hypothesis of population mean is to?
A recent census of a small town in Michigan showed that 60% of the residents are male, 20% have college degrees, and 15% are both male and college graduates.
Country A and Country C spends about the same amount on average per person per year. Which has the greater spread?
