A computer software vendor wants to estimate the number of times a computer will crash with its new operating system over the course of a year. A system administrator installs the operating system on a random sample of 34 computers. At the end of a year, the sample mean number of crashes is 5.6, with a standard deviation of 2.2. Find the confidence interval at a 90% confidence level for the mean number of crashes a computer will have with the new operating system over the course of a year.

answer: number of steps anna and todd walk 150 and 250 respectively.

step-by-step explanation:

since we have given that

for every 3 steps of anna's steps , todd made 5 steps .

so, there will be ratio i.e.

so, the number of steps anna walk = 3x

the number of steps todd walk = 5x

according to question,

so,

number of steps anna walk is given by

number of   steps todd walk is given by

obviously it is c. 75/85
