After rigorous statistical analyses have shown a very low likelihood (usually 5% or less) of a result having occurred by chance alone, the result is said to be ____.​ a.

Given the following data for an imaginary superhero universe:    Flying   Telepathy   Super Strength  Female 70 75 56 Male 6 98 54   What is the empirical probability that a randomly selected female superhero will have telepathy? Answer in decimal form.  Round to 3 decimal places as needed.

In an article that appears on a website,† Carlton Gunn, a public defender in Seattle, Washington, wrote about how he uses statistics in his work as an attorney. He states the following. I personally have used statistics in trying to challenge the reliability of drug testing results. Suppose the chance of a mistake in the taking and processing of a urine sample for a drug test is just 1 in 100. And your client has a "dirty" (i.e., positive) test result. Only a 1 in 100 chance that it could be wrong? Not necessarily. If the vast majority of all tests given—say 99 in 100—are truly clean, then you get one false dirty and one true dirty in every 100 tests, so that half of the dirty tests are false. Define the following events as given below. TD = event that the test result is dirty TC = event that the test result is clean D = event that the person tested is actually dirty C = event that the person tested is actually clean (a) Using the information in the quote, compute the following…

The U.S. Health Department reported that 40% of households had both a wireless phone and a landline. Assume that in a simple random sample of 300 households, 105 are found to have both services. With this information answer the following questions: What is the population proportion, π? What is the sample proportion, p? What is the standard error of the sample proportion? In the sampling distribution of the proportion, what is the probability that a sample of this size would result in a sample proportion at least 35%?

For a right sided, one-tailed test, the test statistic z is calculated to be zero. The p-value corresponding to this calculated test statistic is, a. 0.50 b. zero c. -0.50 d. 1.00

Suppose a sample of O-nings waS obtained and the wall thickness (in inches) of each was recorded. Use a normal probability plot to assess whether the sample data could have a a come from a population that is normally distnbuted. 0.190 0.194 0.199 0.205 E 0. 0.214 0.213 0.233 0.249 0.264 0.276 0.288 0.292 306 0.308 0.311 0.317 Click here to vew the table of cntical values for normal probability_plots] to Click here to view page 1 of the standard normal distribution table Click here to vew page 2 of the standard normal distribution table 2 b ◦ Using the correlation coeficient of the normal probability plot, is it reasonable to conclude that the population is normally distnibuted? Select the correct choice below and fll in the answer boxes within your choice. (Round to three decimal places as needed.) ○ A. Yes. The correlation between the expected z-scores and the observed data, Therefore, it is not reasonable to conclude that the data come from a noral population. exceeds the critical…
