On a multiple-choice test, each question has 4 possible answers. A student does not know

Mumz [18]

Answer:

42.1875% probability that the student gets all three questions wrong

Step-by-step explanation:

For each question, there are only two possible outcomes. Either the student gets it wrong, or he does not. The probability of the student getting a question wrong is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probabily distribution:

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

On a multiple-choice test, each question has 4 possible answers.

One of these options is correct and the other 3 are wrong. We want to find the probability of getting questions wrong. So $p = \frac{3}{4} = 0.75$

Three question:

This means that $n = 3$

What is the probability that the student gets all three questions wrong?

This is P(X = 3).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 3) = C_{3,3}.(0.75)^{3}.(0.25)^{0} = 0.421875$

42.1875% probability that the student gets all three questions wrong

1. The number of customers in a restaurant during the peak hour of each day for a month varied

Gnom [1K]

Step-by-step explanation:

First we must calculate the interquartile range (IQR), using this equation:

$IQR = Q_{3} - Q_{1}$

Based on the information provided we fill in:

$IQR = 58 - 45$

$IQR = 13$

In order to find what the range for the data set is we need to use the Interquartile Rule:

$Q_{1}-1.5$ × $IQR\\$

$Q_{3}+1.5$ × $IQR\\$

$1.5$ × $13 = 19.5$

Now we plugin in:

$45 - 19.5 = 25.5\\$

$58 + 19.5 = 77.5$

Any number below 25.5 is a possible outlier and any number above 77.5 is a possible outlier.

Answer:

Based on the results of the calculations, 25 could be a possible outlier in the data set.
