A teacher wants to estimate the mean time (in minutes) that students take to go from one classroom to the next. His research assistant uses the sample time of 42 students to report the confidence interval as [7.40, 8.60]. [You may find it useful to reference the t table.] a. Find the sample mean time used to compute the confidence interval. (Round intermediate calculations to 4 decimal places and final answer to the nearest whole number.) b. Determine the confidence level if the sample standard deviation used for the interval is 1.606. (Round intermediate calculations to at least 4 decimal places. Round "t" value to 3 decimal places and final answer to the nearest whole number.)

A random sample of 36 observations is drawn from a population with a mean equal to 66 and a standard deviation equal to 12. What is the mean and the standard deviation of the sampling distribution of x̄? μ = 66 σ = 2 Describe the shape of the sampling distribution of x̄. Does this answer depend on the sample size? The shape is that of a distribution and depend on the sample size. Calculate the z-score corresponding to a value of x̄ = 63.6. Calculate the z-score corresponding to a value of x̄ = 69.2. Find P(x̄ ≥ 63.6) (to 4 decimals) Find P(x̄ < 69.2) (to 4 decimals) Find P(63.6 ≤ x̄ ≤ 69.2) (to 4 decimals) There is a 60% chance that the value of x̄ is above (to 4 decimals).

Many people believe that they can tell the difference between Coke and Pepsi. Other people say that the two brands cannot be distinguished. To test this, a random sample of 20 adults was selected to participate in a test. After being blindfolded, each person was given a small taste of either Coke or Pepsi and asked to indicate which brand soft drink it was. If people really can't tell the difference, what is the probability that fewer than 6 people will guess correctly

Assume that females have pulse rates that are normally distributed with a mean of mu equals 72.0 beats per minute and a standard deviation of sigma equals 12.5 beats per minute. Complete parts (a) through (c) below. (a) If 1 adult female is randomly selected, find the probability that her pulse rate is between 66 beats per minute and 78 beats per minute. The probability is? (b) If 4 adult females are randomly selected, find the probability that they have pulse rates with a mean between 66 beats per minute and 78 beats per minute The probability is? (c) Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
