The probability that a random vehicle gets between 28 and 36 miles per gallon is 0.3333.
<h3>What's probability?</h3>
Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true. The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
Given that,
a = 23
b = 47
P(c < x < d) = (d - c) / (b - a)
P(28 < x < 36) = (36 - 28) / (47 - 23) = 0.3333
Probability = 0.3333

So you would do .39 times .39
that is .1521
If you round it is .152
.152 times 100 equals 15.2%
Answer:
The sample size for the data set = 56
Step-by-step explanation:
The sample size or number of individuals (n) is gotten from a histogram by summing up the total frequencies of occurrences.
In this example, the frequencies are: 2 4 6 8 10 12 14
Therefore, the sample size (n) is calculated as follows:
n = 2 + 4 + 6 + 8 + 10 + 12 + 14 = 56
Therefore the sample size for the data set = 56
