not correct and 35% for the answers

Answer:

  • The owner's prediction is Not Correct .
  • . Based on the samples,  about 35% of the books sold each week are fiction books.

Step-by-step explanation:

The owner of a bookstore predicts that over 50% of the books she sells each week are fiction books.

Based on the table of randomly selected sample we see that in week 1 there are 50 fiction books out of total 150 books.

so, the percentage of fiction books are:

[tex]\dfrac{50}{150}\times 100\\\\=33.33\%[/tex]

Similarly in the second week i.e. week 2 the number of fiction books are 55 out of 150 books so, the percentage of fiction books in week 2 are:

[tex]\dfrac{55}{150}\times 100\\\\=36.66\%[/tex]

Hence,

  • The owner's prediction is Not Correct .
  • . Based on the samples,  about 35% of the books sold each week are fiction books.
