The international bottled water association says that americans on the average drink 4.6 (8-oz.) serving of water a day (https://www.bottledwater.org/public/summary.htm) Assuming that the number of 8-oz. servings of water is approximately normally distributed with a standard deviation of 1.4 serving, what proportion of americans drink
a. more than the recommended 8 servingsb. less than half the recommended 8 servings
Suppose it is desired to estimate the population mean number of miles with a margin of error of ± 2 miles at 95% confidence. Do the data provide this desired level of precision? What action, if any, would you recommend be taken?
What does the binomial distribution chart look like? Can I use Excel to come up with this chart?
How large a sample is needed to estimate the true proportion of home owners who have vegetable gardens to within 0.04 with 98% confidence?
Be sure to specifically identify the statistical formulas and what additional data you would need to determine your estimate(s).
If true explain and if false give an example. a. The significance level of a statistical test is equal to the probability that the null hypothesis is true. b. If the significance level of a test is decreased, the power of the test would be expected t..
Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and a standard deviation of 1 degrees C.
The standard deviation of is usually called the A. randomized standard error B. standard error of the sample C. standard error of the population D. standard error of the mean
In the following observational studies, describe changes that could be made to the data collection process that would result in an experiment rather than an observation study. Also, offer suggestions about unseen biases or lurking variables that m..
