In a certain town, 30% of adults have a college degree. The accompanying table describes the probability distribution for the number of adults (among 4 randomly selected adults) who have a college degree. Find the standard deviation for the probability distribution.
Estimate the population means growth in 1 year for 14-year-old boys. Make a point estimate and an 80% confidence interval estimate.
Test whether the mean rate is less than 6%. Use P-value approach.
In a simple random sample of 1000 households, 150 households happen to own a barbecue grill. Based on the characteristics of the population, the expected number of grill owners in the sample was 180.
First part of this theorem allows a problem solver to compute probabilities about sample means regardless of whether a population is normally distributed.
Given that standard deviation process=4.7 and standard deviation gage=3.4, what is the total standard deviation in data from this process?
What is the probability that an improperly adjusted machine will produce five or more items before it is stopped? What is the average number of items an improperly adjusted machine will produce before being stopped?
What is the mean and standard deviation of the sampling distribution of x-bar assuming that mean =20 and standard deviation equals the square root of 20?
A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is less than 1 in every one thousand. State the null hypothesis and the alternative hypothesis for a test of significance.
Suppose that n trials of a binomial experiment result in no successes.
Find the test statistic P-value, and critical value, and state the final conclusion.
You might find the probabilities using the Table or software of your choice. Please explain how you obtained your results.
If a student guesses on each question, what is the probability that the student will pass the test?
