9. Determines the average, median and standard deviation of each of the distributions to a variable (age, girl reaction time and boys reaction time).What interpretations can you make of it? B.) For each of the three two-variable distributions, make a graphical representation using a technological tool and calculate the values that can be used to interpret them. C.) Interpret graphic representations and draw conclusions.
Use z scores to compare the given values. The tallest living man at one time had a height of 238 cm. The shortest living man at that time had a height of 142.4 cm. Heights of men at that time had a mean of 175.45 cm and a standard deviation of 5.59 cm. Which of these two men had the height that was more extreme? ... Since the z score for the tallest man is z = 0 and the z score for the shortest man is z = the man had the height that was Im- more extreme. (Round to two decimal places.) shortest tallest
The mean output of solar cells of three types is measured six times under random light intensity over a period of 5 minutes, yielding the results shown. Research question: Is the mean solar cell output the same for all cell types?
to qualify for membership in a certain high-IQ society a person must score in the upper 2% of the population on an IQ test. the minimum IQ score to be in the upper 2% is a 140.5 if Iq scores are normanlly distributed with a standrd deviation of 10, what is the mean IQ score?
Three students were applying to the same graduate school. They came from schools with different grading systems. Thuy is Vichet is Kamala is Number Number Student GPA School Thuy Number 2.5 Vichet 86 Table 2.74 School Average 2.8 80 Kamala 8.5 8.3 How many standard deviations is each student away from hiir school average? If the student GPA is higher than his school average, enter this as a positive number. If the student GPA is lower than his school average, enter this as a negative number. Average GPA GPA School Standard Deviation 0.8 10 0.5 standard deviations from Thuy's school average. standard deviations from Vichet's school average. standard deviations from Kamala's school average.
Consider two populations of students. Both populations are the same size (1000). The first population consists of all students at a grade school (grades 1-5). The second population consists of all students at a middle school (grades 6-8). Which school's population is more likely to have a larger standard deviation in the age of its students? a) The grade school's population is more likely to have the larger standard deviation. b) The middle school's population is more likely to have the larger standard deviation. c) They would most likely have the same standard deviation for age. a) It is impossible to say without more information.
A distributor's average daily customer demand is 400 units. The standard deviation of customer demand is 30 units. If the distributor would like to maintain a 98% service level (Z score = 2.05) and the supplier's lead time is 9 days, how much safety stock should be held? O 123 units O 185 units O 36,000 units O 554 units

3 In the 1800s, German physician Carl Reinhold, took millions of axillary (i.e. armpit) temperatures from soldiers. This study established that body temperature is normally distributed and the standard normal human body temperature is 98.6℉ with a standard deviation of 0.72 ℉. In a recent study, American researchers obtained 5,000 axillary temperatures from a Los Angeles hospital. The mean of these temperature readings was 97.9 ℉. Assuming a Type I error risk of no more than 5%, did the findings support the theory that human, body temperature has decreased since the 1800s? What is the standard error? (round to nearest hundredth) What is the Z obt? (round to the nearest tenth)
Analysts of traffic control systems believe that the average speed of heavy vehicles on highways has decreased after passing an ordinance of high penalty to regulate over speeding. The average speed for a random selection of 36 trucks was found to be 55 mph with a standard deviation of 5 mph. The speed before the ordinance was passed was an average of up to 57 mph on these highways.Compute the value of the test statistic. Group of answer choices 0.40 -0.40 2.40 -5.37 -2.40
