- Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Let Z represent the reading of this thermometer at freezing. What reading separates the highest 5.6% from the rest? That is, if P(z> c) = 0.056, find c.

- For samples of the specified size from the population described, find the mean and standard deviation of the sample mean x. do The National Weather Service keeps records of rainfall in valleys. Records indicate that in a certain valley, the annual rainfall has a mean of 78 inches and a standard deviation of 10 inches. Suppose the rainfalls are sampled during randomly picked years, and x is the mean amount of rain in these years. For samples of size 25, determine the mean and standard deviation of x.

The standard deviation for the population is o = 4. OTrue O FalseA person's body mass index (BMI) is computed by dividing the weight (kg) by the square of height (m). The accompanying table contains the BMI statistics for random samples of males and females. Assume that the two samples are independent simple random samples selected from normally distributedpopulations, and do not assume that the population standard deviations are equal. Let population 1 be females. Female BMI: n=69 x=29.14 s=7.41 Male BMI: n=79 x=28.18 s=5.24 The test statistic is The P-value is Construct a confidence interval appropriate for testing the claim in part (a). The ___% confidence interval estimate is ___<μ1−μ2<___.
- One of the ways in which doctors try to determine how long a single dose of pain reliever will provide relief is to measure the drug’s half-life, which is the length of time it takes for one-half of the dose to be eliminated from the body. A report of the National Institutes of Health states that the standard deviation of the half-life of the pain reliever oxycodone is σ = 1.43 hours. Assume that a sample of 25 patients is given the drug, and the sample standard deviation of the half-lives was s = 1.5 hours. Assume the population is normally distributed. Can you conclude that the true standard deviation is greater than the value reported by the National Institutes of Health?The contents of 33 cans of Coke have a mean of x¯=12.15 and a standard deviation of s=0.12. Find the value of the test statistic t for the claim that the population mean isμ=12.using the values on the first picture, can you solve no. 2?

(Hint: Sketch the distri- bution and locate the two scores on your sketch.)If the distribution of weight of newborn babies in Maryland is normally distributed with a mean of 3.57 kilograms and a standard deviation of 0.93 kilograms, find the weights that correspond to the following z- scores. Use the formula z = 4 decimal places. a. z = -1.55 X = b. z = 1.49 X = kilograms kilograms Submit Question X- σ μ where μl is the mean, o is the standard deviation, and x is the weight. Round toA sample of 12 measurements has a mean of 25 and a standard deviation of 4.5. Suppose that the sample is enlarged to 14 measurements, by including two additional measurements having a common value of 25 each. Find the mean of the sample of 14 measurements. Find the standard deviation of the sample of 14 measurements. S =
