Suppose that resting pulse rates among healthy adults are normally distributed with a mean of 73 beats per minute and a standard deviation of20 beats per minute.Use this table or the ALEKS calculator to find the percentage of healthy adults who have resting pulse rates that are less than 98 beats perminute. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example98.23%).0%

It is commonly believed that the mean body temperature of a healthy adult is 98.6∘F98.6∘F. You are not entirely convinced. You believe that it is not 98.6∘F98.6∘F. You collected data using 36 healthy people and found that they had a mean body temperature of 98.21∘F98.21∘F with a standard deviaiton of 1.18∘F1.18∘F. Use a 0.05 significance level to test the claim that the mean body temperature of a healthy adult is not 98.6∘F98.6∘F.a) Identify the null and alternative hypotheses?H0H0: ? p = p ≠ p < p > p ≤ p ≥ μ = μ ≠ μ < μ > μ ≤ μ ≥ H1H1: ? p = p ≠ p < p > p ≤ p ≥ μ = μ ≠ μ < μ > μ ≤ μ ≥ b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance level.d) Calculate your test statistic.

. Students may be classified as having a math dysfunction—and not have to take statistics—if they score below the 25th percentile on a diagnostic test. The m of the test is 75 and sX 10. Approximately what raw score is the cutoff score needed to avoid taking statistics?
A student who took Stat 2 last semester learns that their overall course score was at the 85th percentile. Assuming that a histogram of all the Stat 2 course scores from last semester follows the normal curve, this means that this student had a score that was how many SDs above the average score? Choose the answer that is closest. Group of answer choices 1.15 1.05 1.10 1.0 PreviousNext

prove that If we multiply the data values by a constant (say, c), value of geometric mean will be affected. how this will affect the geometric mean? Use the equation in image to prove it, and give an example.
A certain manufacturer makes 400w light bulbs. Assume that these light bulbs have lifetimes that are normally distributed with a mean lifetime of 480 hours and a standard deviation of 50 hours. Use this table or the ALEKS calculator to find the percentage of light bulbs with lifetimes shorter than 384 hours. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%). % X Español
A race director is preparing for an upcoming marathon and estimates that the mean time to finish is 315 minutes. Assume that the times are normally distributed, with a standard deviation of 60 minutes. Use this table or the ALEKS calculator to find the percentage of times that are shorter than 453 minutes. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%). % X
In California, we need more rain to sustain the health of our natural environment, argriculture, and economic. A group of statistics students in Oxnard College recorded the amount of rain during 2016-2017 school year, measuring the intensity by the inches of rain, and the results were: Inches of Rain 1 2 3 4 5 6 Frequency 1 2 8 2 1 1 The mean (¯xx¯) rain intensity: inches (Please show your answer to 1 decimal place.)The median rain intensity: inchesThe mode rain intensity: inches (Please separate your answers by ',' in the bimodal situation.
