The distribution of heights in a population of women is approximately normal. Sixteen percent of the women have heights less than 62 inches. About 97.5% of the women have heights less than 71 inches. Use the empirical rule to estimate the mean and standard deviation of the heights in this population. Mean: K inches Standard Deviation: inches
The average age of trees in a large local park is 60 years with a standard deviation of 2.2 years A simple random sample of 4 trees is selected, and the sample mean age z of these trees is computed. The percentage of trees older than 60.1 years is
Babies: A sample of 25 one-year-old girls had a mean weight of 24.1 pounds with a standard deviation of 4.3 pounds. Assume that the population of weights is normally distributed. A pediatrician claims that the standard deviation of the weights of one-year-old girls is greater than 7 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the =α0.05 level of significance.
Suppose a normal distribution has a mean of 79 and a standard deviation of 7. What is P(x < 65)? A. 0.975 В. 0.84 С. 0.025 D. 0.16
Assume that Christmas trees sold in a farm have heights that are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. Find the value of the quartile Q3 (75% of trees are shorter than this height). 65.3 inches 64.3 inches 66.1 inches O 67.8 inches
If the standard deviation of hole diameter exceeds 0.01 millimeters, there is an unacceptably high probability that the rivet will not fit. Suppose that in a sample of 15, the standard deviation is 0.008 millimeter. Is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeter? Use α = 0.10. What is the Statistical Decision in statement form?
Consider a value to be significantly low if its z score less than or equal to - 2 or consider a value to be significantly high if its z score is greater than or equal to 2. A data set lists weights (grams) of a type of coin. Those weights have a mean of 5.62152 g and a standard deviation of 0.05197 g. Identify the weights that are significantly low or significantly high. What weights are significantly low? Select the correct answer below and fill in the answer box(es) to complete your choice. O A. Weights that are greater than . (Round to five decimal places as needed.) (Round to five decimal places as needed.) B. Weights that are less than C. Weights that are between and.

A hospital administrator believes that the standard deviation of the number of people using outpatient survey per day is greater than 8. A random sample of 15 days is selected. The data are shown below. At α = 0.1, is there enough evidence to support the administrator’s claim? Show your work and indicate the conclusion and assume that the variable is normally distributed.25, 30, 5, 15, 18, 42, 16, 9, 10, 12, 12, 38, 8, 14, 27.
10) A county is considering raising the speed limit on a road because they claim that the mean speed of vehicles is greater than 40 mi/hr. A random sample of 15 vehicles has a mean speed of 43 mil/hr and a standard deviation of 4.4 mi/hr. Assume that speeds follow a normal distribution. What statistical test should be used to test the claim? (pick one of the options) 1. t-test 2. 2.73 3. 15 4. 10.9 5. 14 6. z-test 7. 2.52 8. 2.64 Calculate the value of standardized test statistic.

Cell Phone Lifetimes A recent study of the lifetimes of cell phones found the average is 23.8 months. The standard deviation is 5.8 months. If a company provides its 33 employees with a cell phone, find the probability that the mean lifetime of these phones will be less than 23.8 months. Assume cell phone life is a normally distributed variable, the sample is taken from a large population, and the correction factor can be ignored. Use a TI-83 Plus/TI-84 Plus calculator. Round your answer to at least four decimal places. <PX23.8)=
