Question

Accepted characters: numbers, decimal point markers (period or comma), sign indicators (.), spaces (e g. as thousands separator, 5 000). 'E' or "e" (used in scientific notation). Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values. For example: (1 +1i) is valid whereas (1 + i) is not. (0+9i) is valid whereas (9i) is not. The histogram below represents scores achieved by 250 job applicants on a personality profile. What percentage of the Job applicants scored below 60? Place your answer in the blank, rounded to 2 decimal places. Do not use a percentage sign (%). For example. 44.44 would be a legitimate answer.

Explanation / Answer

In this histogram,

P(below 60) = 1 - P(60 and above)

As in the figure,

P(60 and above) = 0.10

Then

P(below 60) = 1 - P(60 and above) = 1 - 0.10 = 0.90

P(below 60) = 90% [ANSWER: 90]
