Below are survival times (in days) of 13 guinea pigs that were injected with a bacterial infection in a medical study: 91 83 84 79 91 93 95 97 97 120 101 105 98

Are there any outliers in the data set above? Use the 1.5 IQR rule to check.

Q1 =

Q3 =

IQR =

IQR(1.5) =

Q3 + IQR(1.5) =
(Upper outlier)

Q1 - IQR(1.5) =
(Lower outlier)

Name any outliers in the set of data:

If an x intercept only touches the x axis it means it has a multiplicity of 2. if an intercept goes through the axis it has a multiplicity of 1 true false

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
