Aprogrammer plans to develop a new software system. in planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. how many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than two percentage points question mark s?

complete parts (a) through (c) below.

a) assume that nothing is known about the percentage of computers with new operating systems. n= up to the nearest integer.)

b) assume that a recent survey suggests that about 96% of computers use a new operating system. n= up to the nearest integer.)

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

the eight graders whould be the answer

step-by-step explanation: could you give me 5 stars

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.
