Answer:
3.59 minutes
Explanation:
We solve this question using z score formula
Using Excel
Z-SCORE= (DataPoint-AVERAGE(DataSet))/STDEV(DataSet)
IN EXCEL,
AVERAGE, an excel function that calculates the Average of data set
STDEV.S: calculates the standard deviation while treating the data as a ‘sample’ of a population.
STDEV.P: This function calculates the standard deviation while treating the data as the entire population.
Z score formula = x - μ/σ
x = ?? μ = 2.5 minutes σ = 0.5 minutes
We are asked : If 1.5% of the callers are put on hold for longer than x minutes, what is the value of x?
Hence, Longer than = Greater than =
100 - 1.5%
= 100 - 0.015
= 0.985 ( 98.5%)
Using Excel we calculate = z score for 98.5 percentile
= 2.1701
Z score = x - μ/σ
2.1701 = x - 2.5/0.5
2.1701 × 0.5 = x - 2.5
1.08505 = x - 2.5
x = 1.08505 + 2.5
x = 3.58505
Approximately to 2 decimal places = 3.59 minutes
Therefore, 1.5% of the callers are put on hold for longer than 3.59 minutes.

Answer:
Create the student class object which inherit the printinfo() from the abstract class People
Explanation:
Classes in object-oriented programming are blueprints of a defined type of data structure.
An object of an abstract class cannot be instantiated. So, the People class in question, is only inherited by the Student class which able to use the define printinfo() method.
Hi!
The Clipboard in Microsoft Word is great for having more than just one paste option via the paste command.
Using the Clipboard, you can hold up to 24 items that are copied. This makes it efficient if you have a lot of data you would like to paste.
Hopefully, this helps! =)
