Answer:

0.568

Step-by-step explanation:

P( e-book) = 0.28, P(On the bestseller list) = 0.4

Since event e-book and bestseller list are independent,

( Using formula, P( A OR B) = P(A) + P(B) - P( A AND B) )

P(e-book AND On the bestseller list) = P( e-book) * P(On the bestseller list)

P( e-book OR on the bestseller list) = P( e-book) + P(On the bestseller list)

- P( e-book) * P(On the bestseller list)

= 0.28 + 0.4 - 0.28 * 0.4

= 0.568

Gnesinka [82]

Answer:

a range of values such that the probability is C % that a rndomly selected data value is in that range

Step-by-step explanation:

complete question is:

Select the proper interpretation of a confidence interval for a mean at a confidence level of C % .

a range of values produced by a method such that C % of confidence intervals produced the same way contain the sample mean

a range of values such that the probability is C % that a randomly selected data value is in that range

a range of values that contains C % of the sample data in a very large number of samples of the same size

a range of values constructed using a procedure that will develop a range that contains the population mean C % of the time

a range of values such that the probability is C % that the population mean is in that range

Mazyrski [523]

Answer:

12.

Step-by-step explanation:

This is how to round 12.36 to the nearest whole number. In other words, this is how to round 12.36 to the nearest integer.

12.36 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 12

Fractional Part: 36

Our goal is to round it so we only have an integer part using the following rules:

If the first digit in the fractional part of 12.36 is less than 5 then we simply remove the fractional part to get the answer.

If the first digit in the fractional part of 12.36 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.

The first digit in the fractional part is 3 and 3 is less than 5. Therefore, we simply remove the fractional part to get 12.36 rounded to the nearest whole number as:
