We require a total of 144 birthday candles for the 12 parties.

Step-by-step explanation:

As a caterer focused on children’s birthday celebrations, you have 12 events to cater to in the upcoming week, each requiring 2 cakes. Each cake will be adorned with 6 candles.

Which of the following can be reasonably modeled by a normal distribution?
Inessa [12570]

Response:

A) The preferred colors of kindergarten students

B) The growth heights of tomato plants that were all planted on the same day

E) The age ratings (G, PG, PG-13, R) assigned to films released in 2019

Clarification:

A normal distribution is characterized by a bell-shaped curve where a majority of data points cluster near the average. Instances pertaining to intelligence, height, blood pressure, student evaluations, shoe sizes, birth weights, citizen incomes, stock market data, and random events like rolling dice or flipping coins, are examples that can be well-described using a normal distribution. The central limit theorem is applicable here, considering that various independent factors impact a particular characteristic.
