ion with a mean of 14 g/dL and a standard deviation of 1. From the given data, we can conclude that about people have hemoglobin levels less than 13, and about people have hemoglobin levels greater than 14.

Since the data follows a normal distribution, the 68-95-97 rule can be used to describe the number of people falling under N standard deviations from the mean. Since the standard deviation is 1, hemoglobin levels of 13 -15 g/dL contains 68% of the sample, or 136 people. This means the 32 people have less than 13 g/dL and 32 people have more than 15 g/dL.

Answer:

  • 20 taffy bags and 15 caramel candy bags

Step-by-step explanation:

<u>Given:</u>

  • t = the number of taffy bags
  • c = the number of caramel bags
  • Number of taffy's are 5 more than caramel bags
  • Taffy bags weigh 8 ounces and caramel bags weigh 16 ounces
  • Total weight is 400 ounces

<u>Equations:</u>

  • t = c + 5             (the difference in number of bags)
  • 8t + 16c = 400  (the weight of the bags)

<u>Simplify the second equation by dividing all terms by 8:</u>

  • t + 2c = 50

<u>Substitute t and solve for c:</u>

  • c + 5 + 2c = 50
  • 3c = 50 - 5
  • 3c = 45
  • c = 45/3
  • c = 15

<u>Find the value of t:</u>

  • t = 15 + 5 = 20

<u>Answer:</u>

  • 20 taffy bags and 15 caramel candy bags
