A vendor converts the weights on the packages she sends from pounds to kilograms (1 kg ≈ 2.20 lb). The mean weight of the package was 21 lb with standard deviation of 0.31 lb. After repackaging (converting units), the mean becomes kg (round your answer to 2 decimal places), and the standard deviation becomes kg (round your answer to 2 decimal places).
Assume that adults have IQ scores that are normally distributed with a mean of u = 100 and a standard deviation o = 15. Find the probability that a randomly selected adult has an IQ between 84 and 116. Click to view page 1 of the table. Click to view page 2 of the table. The probability that a randomly selected adult has an IQ between 84 and 116 is (Type an integer or decimal rounded to four decimal places as needed.)
A California lake has been stocked with rainbow trout. These trout have an average length of 24 inches, with a standard deviation of 3 inches. Someone goes fishing and catches a trout that is 26.25 inches long. Express the length of this trout in standard units, relative to all the trout that were used to stock the lake. Choose the answer below that is closest.
A group of adult males has foot lengths with a mean of 26.63 cm and a standard deviation of 1.32 cm. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is the adult male foot length of 29.8 cm significantly low or significantly high? Explain. Significantly low values are nothing cm or lower. (Type an integer or a decimal. Do not round.) Significantly high values are nothing cm or higher. (Type an integer or a decimal. Do not round.) Select the correct choice below and fill in the answer box(es) to complete your choice. A. The adult male foot length of 29.8 cm is not significant because it is between nothing cm and nothing cm. (Type integers or decimals. Do not round.) B. The adult male foot length of 29.8 cm is significantly low because it is less than nothing cm. (Type an integer or a decimal. Do not round.) C. The adult male foot length of 29.8 cm is significantly high because it is…
A student scores 74 on a geography test and 264 on a mathematics test. The geography test has a mean of 80 and a standard deviation of 5. The mathematics test has a mean of 300 and a standard deviation of 24. If the data for both tests are normally distributed, on which test did the student score better relative to the other students in each class? OA. The student scored better on the mathematics test. OB. The student scored better on the geography test. OC. The student scored the same on both tests.
Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 77.8 Mbps. The complete list of 50 data speeds has a mean of x= 16.56 Mbps. And a standard deviation of s= 35.08 Mbps. Convert the carriers highest data speed to a z score
A group of adult males has foot lengths with a mean of 27.75 cm and a standard deviation of 1.11 cm. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is the adult male foot length of 30.6 cm significantly low or significantly high? Explain. Significantly low values are cm or lower. (Type an integer or a decimal. Do not round.) Significantly high values are cm or higher. (Type an integer or a decimal. Do not round.) Select the correct choice below and fill in the answer box(es) to complete your choice. The adult male foot length of 30.6 cm is significantly high because it is greater than O A. (Type an integer or a decimal. Do not round.) cm. The adult male foot length of 30.6 cm is significantly low because it is less than О в. (Type an integer or a decimal. Do not round.) cm. The adult male foot length of 30.6 cm is not significant because it is between OC. cm and cm. (Type integers or decimals. Do not round.)
For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 38beats per minute, the mean of the listed pulse rates is x =73.0 beats per minute, and their standard deviation is sequals=23.2 beats per minute. a. What is the difference between the pulse rate of 38 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of 38 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between minus−2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 38 beats per minute significant?
