What is the probability that a book selected at random is fiction, given that it costs less than $10?

Find the mean, median, and mode of the data set. Round to the nearest tenth.

2, 10, 6, 9, 1, 15, 11, 10, 15, 13, 15

• Mean = 9.7

  Median = 10

  Mode = 15

• Mean = 8.9

  Median = 10

  Mode = 8

• Mean = 9.7

  Median = 8

  Mode = 15

• Mean = 8.9

  Median = 10

  Mode = 15

What are the mean, variance, and standard deviation of these values?
Round to nearest tenth.

• mean = 93.5

  variance = 245.6

  standard deviation = 17.2

• mean = 87.5

  variance = 245.6

  standard deviation = 15.7

• mean = 87.5

  variance = 4

  standard deviation = 15.7

• mean = 93.5

  variance = 4

  standard deviation = 17.2
