By how many times does the sample size have to be increased to decrease the margin of error by a facgtor of 1/9?

Identify the type I error and the type II error that correspond to the given hypothesis.   The percentage of households with Internet access is greater than 60%.

State the number of degrees of freedom available for determining the​ within-samples variation.

The difference between the largest and the smallest data values is the O variance O interquartile range O range O coefficient of variation

A study was conducted to see of airbags save lives. The table below lists the results from a simple random sample of front-seat occupants involved in car crashes.    Airbag Available No Airbag Available Occupant Fatalities 41 52 Total number of occupants 11,541 9,853   What is the sample proportion of fatalities where there were no airbags available, p2? What is the difference in the two proportions, D? What is the standard error of the difference, SED?

You can reduce the risk of a Type I error by using a larger sample. True or False?

What is the value of SS (sum of squares deviations) for the following population? 1,1,1,5

What are the values for SS and variance for the following sample of n = 3 scores? Sample:  8, 5, 2

When solving a problem related to one sample and the confidence interval of variance. Suppose the sample size is n. What is the degree of freedom we will use?
