Most people think that the "normal adult body temperature is 98.6°F in a more recent study, researchers reported that a more accurate figure may be 97 9°F. Furthermore, the standard deviation appeared to be around 0.4°F Assume that a Normal model is appropriate. Complete parts a through c below.

C. Using the 68-95-99 7 Rule, about 95% of the body temperatures are expected to be between 97.1 °F and 98.7 °F
(Use ascending order. Round to one decimal place as needed)

b) What fraction of people would be expected to have body temperatures above 986°F?

4%

(Round to two decimal places as needed)

c) Below what body temperature are the coolest 25% of all people?
%
(Round to one decimal place as needed)

step-by-step explanation:

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
