Based on a​ poll, among adults who regret getting​ tattoos, 16 16​% say that they were too young when they got their tattoos. Assume that four four adults who regret getting tattoos are randomly​ selected, and find the indicated probability. Complete parts​ (a) through​ (d) below. a.

In a Gallup poll, 1011 adults were randomly selected and asked if they consume alcoholic beverages. Of this sample, 64% said they did. Check requirements before computing confidence interval If requirements are met, use StatCrunch to obtain a 90% confidence interval for the proportion of all adults who consume alcoholic beverages. c. Write interpretation of the confidence interval.

A simple random sample of 16 adults drawn from a certain population of adults yielded a mean weight of 63kg. Assume that weights in the population are approximately normally distributed with a variance of 49. Do the sample data provide sufficient evidence for us to conclude that the mean weight for the population is less than 70 kg? Let the probability of committing a type I error be .01. 1. Write the hypotheses, indicate the claim 2. find the critical...

The systolic blood pressure of 16 students was measured before a test. The blood pressure from this sample averaged 165, with a standard deviation of 40. a) Compute the approximate 95% confidence interval for mean systolic blood pressure, and make a sketch illustrating these confidence intervals b) If a mean blood pressure above 130 is considered “stressed”, what do your calculations show regarding the probability that the observed mean is above the “stressed” level.

The foot size of each of 16 men was measured, resulting in the sample mean of 27.32 cm. Assume that the distribution of foot sizes is normal with sigma = 1.2 cm. a) Test if the population mean of men’s foot sizes is 28.0 cm using alpha = 0.01. b) If alpha = 0.01 is used, what is the probability of a type II error when the population mean is 27.0 cm? c) Find the sample size required to ensure...

1. A forester measured a sample of trees in a tract of land being sold for a lumber harvest. Among 27 trees, she found a mean diameter of 10.4 inches and a standard deviation of 4.7 inches. Suppose her sample gives an accurate representation of the entire tract of land and that the tree diameters follow a normal distribution. Round to 2 decimal places, when applicable. (a) Sketch a graph of the distribution of tree diameters, labeling the mean and...
