When performing a chi-square test for independence, explain how the "cell frequencies under the independence assumption" are calculated. For what purpose are these frequencies calculated?
To test whether the population mean is less than a specified value.
Use frequency distribution to create a probability distribution, determine the (b) mean,(c) variance.
Identify the sampling distribution to be used: the standard normal distribution or the Student's t distribution. Find the critical value(s).
Find out 90% confidence interval for mean grade of all the students in the class.
What is the best estimate of the average tread life for the entire population of these tires?
According to Chebyshev's theorem, proportion of values from data set that is further than 2 standard deviations from the mean is at most?
Determine the sample size needed in order to be 99% confident that the sample proportion of the current customer accounts is within .03 of the true proportion of all current accounts for this company.
The reason why we finish our calculation by dividing range by 4 is that in most data sets 95% of the data values fall within two standard deviations of the mean.
A school tracks the absences of pupils as part of a flu surveillance system. Regular reporting of absences among 25 students in grade 1 are taken, and based on these data, the long-run proportion of absences under normal conditions is estimated to..
A point estimate for the difference between the mean purchases of the users of the two credit cards is:
A sample of 25 students enrolled in the university indicates that X (bar) = $315.4 and s = $43.20.
Estimate the population means growth in 1 year for 14-year-old boys. Make a point estimate and an 80% confidence interval estimate.
