Answer:
a
b
Yes
Step-by-step explanation:
From the question we are told that
The probability that a random selected person of age 40 years or older is a jogger is
The probability that a random selected person of age 40 years or older is a male given that he/she jogs is
Generally the probability that a randomly selected person age 40 years or older is male and jogs
Generally it would be unusual because the probability that a randomly selected person age 40 years or older is male and jogs is greater than 0.05[border line for statistical significance]
Answer:
To be able to determine the unknown range of the number with tolerance given, first we need to determine the 4% of 500. This can be done by multiplying 500 by the decimal equivalent of 4% which is equal to 0.04.
tolerance = (500) x (0.04) = 20
Lower limit: The lower limit is determined by subtracting 20 from 500.
Lower limit = 500 - 20 = 480
Upper limit: The upper limit is determined by adding 20 to the base value 500.
Upper limit = 500 + 20 = 520
The values, therefore, rang from 480 to 500.
<em>ANSWER: 480 - 520</em>

Answer:
1/92
Step-by-step explanation:
There are C(3, 2) = 3 ways to select 2 jelly-filled donuts from the 3 in the box. There are C(24, 2) = 276 ways to select 2 donuts from the box.
The probability that you will select 2 jelly-filled donuts is ...
... 3/276 = 1/92
_____
C(n, k) = n!/(k!(n-k)!)
C(3, 2) = (3·2)/2 = 3
C(24, 2) = (24·23)/2 = 276
Answer:
x≥ 19
Step-by-step explanation:
Let the price of an amusement park ticket is x
If the price of an amusement park ticket is no less than x, therefore, it has to be x or greater than x;
The inequality sign to be used will be the greater than or equal to sign (≥). Hence the required inequality is x≥ 19 where x is the price of an amusement park ticket.
