What is the chance that a person randomly selected off the street was born in May

Mathematics

EastWind [94]3 years ago
8 0

Answer: Eight percent.

Step-by-step explanation: In order to find this, we have to use the probability formula, which is:

The Event We Are Looking For/All of the Events.

In this case, plugging the numbers into the formula we get

May(1)/All the months in the year, including May (12).

Diving this, our answer will be 0.08333..., or rounded up to 0.8

However, since we are only looking for one specific event, we can take the number 100, and divide it by all the events. 12/100 is 8.333..., or rounded to 8.

Answer:

(0.55, 0.75)

Step-by-step explanation:

The range can be estimated to be 6 standard deviations wide.  Therefore, the standard deviation is:

σ = (0.72 - 0.42) / 6

σ = 0.05

The margin of error is ±2σ, so:

ME = ±0.10

Therefore, the interval estimate is:

(0.65 - 0.10, 0.65 + 0.10)

(0.55, 0.75)
