Conduct a one-tailed hypothesis test given the information below.
A certain brand of Green Energy light bulbs was advertised as having an average illumination life-span of 2,500 hours. A random sample of 50 bulbs burned out with a mean life-span of 2,470 hours and a sample standard deviation of 140 hours. With a 0.05 level of significance, is the sample mean less than the advertised mean?
Forty percent of the homes constructed in the Quail Creek area include a security system. Three homes were selected at random. What is the probability all three homes selected have a security system?
A roulette wheel has 38 slots, numbered 0, 00, and 1 to 36. The slots 0 and 00 are colored green, 18 of the others are red, and 18 are black.
Test whether the weight reducers on average will lose less than 10 pounds using P-value approach.
The random variable x is known to be uniformly distributed between 1.0 and 1.5.
A range of values constructed from sample data so that the parameter occurs within that range at a specified probability is:
Determine the probability that at most 4 fish will be killed?
At the .01 significance level, is there a difference in the mean number of times men and Women order take-out dinners in a month? What is the p -value?
Two-liter plastic bottles used for bottling cola are shipped in lots of 100. Suppose the lots are 5 percent defective. Some bottles leak, some are too small, and so forth.
CCI is unable to adjust the mean of the filling process. However, it is able to adjust the standard deviation of the filling process.
If random sample of 9 loads is selected for a weight check, determine the probability that mean weight of those loads is more than 40.60 tons.
You are using a significance level of α = 0.05 to test a claim that p > 0.5. Your sample is a simple random sample of size n = 49. Calculate β for the test, assuming that the true population proportion is 0.7 and showing all work.
Draw a tree diagram to show all possible outcomes of the experiment. Label the probability associated with each stage of the experiment on the appropriate branch.
