A machine cuts circular filters from large rolls of material. If 7.3% of the filters fail to meet specifications, use the normal approximation to the binomial to compute the probability that a sample of 100 of the filters will contain 5 or fewer that fail to meet specifications.
When combining probabilities, to find the probability of one event AND another event, the separate probabilities should be
How strong is the evidence against the company's claim? Based on these data, the P -value of the appropriate test
Suppose that the population follows the normal distribution. Forty trucks are randomly selected and weighed. Within what limits will 95 percent of the sample means occur?
If a random sample of 36 lobster fishermen is selected, what is the probability that their average catch is less than 31.5 pounds? Assume the distribution of the weights of lobster is normal.
the sample revealed a sample mean of 11.7 ounces with a standard deviation of .8 ounces test to see if the population mean is at least 12 ounces using the .05 level of significance.
Your company produces a product in a market that has grown by 10% per year for the past 15 years. According to your estimate, the market is currently at 30% of saturation. Predict sales for the next 20 years.
Is there a significant difference in mean HDL levels among the exercise groups? Run the test at a 5% level of significance.
Identify the sampling distribution to be used: the standard normal distribution or the Student's t distribution. Find the critical value(s).
A researcher used stepwise regression to create regression models to predict Birthrate (births per 1000) using five predictors:
In a two-way ANOVA, there are 4 levels for factor A, 5 levels for factor B, and 3 observations for each combination of factor A and factor B levels. The number of treatments in this experiment equals:
Check that the formula (1) holds when X Unif(0, b). Formula (1) also works for b = 1. Check this when X is an Exponential RV with PDF f(x) = e-x for x 0.
