The more the image resolution would be the more storage it needs. If you think about it when a website tries to load a large image it takes longer than loading a smaller one. Hence, if you have a slow telephone line and need your images to be displayed (loaded) faster, then you have to go with the smallest resolution (the smallest storage).
In a nutshell, your answer will be d) 320x240
Note: 320 x 240 is the dimensions of the image (width x height) and those numbers are measured in pixels which is the unit of measuring images, display screens,...etc. i.e. this image is 320 pixels in width and 240 pixels in height

Explanation:
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.
