Determine which statement is correct/incorrect and please explain the reason behind. Statement I. A discrete random variable can possibly have infinite number of possible values but oftentimes it contains finite number of possible values. Statement II. A continuous random variable can also possibly have finite number of possible values. Statement III. In comparison to the t-distribution, the normal distribution has more values clustered around the mean.

To assess whether two data sets are derived from the same distribution—which need not be known, you can apply the test for _____________ that uses the chi-square distribution. The ________ hypothesis for this test states that the populations of the two data sets come from the same distribution. The test compares the observed values against the expected values if the two populations followed the same distribution. The test is right-tailed. Each observation or cell category must have an expected value of at least ______. Group of answer choices independence, null, four homogeneity, null, five goodness of fit, null, five variance test, alternate, four

16) A company randomly tests 30 components out of a batch of 10,000 to see if the components are defective. The rate of defectives in the past was known to be 0.02. Does this situation result in a binomial distribution? Yes or No (circle one) In your own words explain how this situation does or does not meet each of the 4 criteria required for all binomial distributions. 1. 2. 3. 4.

Ch6. "A carpet manufacturing company is comparing the tensile strengths of two different types of synthetic fiber. Synthetic fiber A used in manufacturing carpet has tensile strength that is normally distributed with mean 75 psi and standard deviation 12 psi, and synthetic fiber B has tensile strength that is 70 psi and standard deviation 12 psi. Random sample of nA = 16 and nB = 9 of fiber specimens are selected. Find the probability that the sample mean of fiber specimen A exceeds the sample mean of fiber specimen B by 4."
