The amount of syrup that people put on their pancakes is normally distributed with mean 64 mL and standard deviation 7 mL. Suppose that 12 randomly selected people are observed pouring syrup on their pancakes. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X N( 64 b. What is the distribution of I? I N( 64 c. If a single randomly selected individual is observed, find the probability that this person consumes is between 64.1 mL and 65.5 mL. d. For the group of 12 pancake eaters, find the probability that the average amount of syrup is between 64.1 mL and 65.5 mL. e. For part d), is the assumption that the distribution is normal necessary? ONOO Yes
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
