Mean Height Calculation:

To find the mean height, we need to add 3 inches to each of the given heights and then calculate the average.

Given Heights:
- 55 inches
- 52 inches
- 48 inches
- 51 inches
- 47 inches
- 47 inches
- 46 inches
- 45 inches
- 50 inches
- 52 inches

Step 1: Add 3 inches to each height
- 55 + 3 = 58 inches
- 52 + 3 = 55 inches
- 48 + 3 = 51 inches
- 51 + 3 = 54 inches
- 47 + 3 = 50 inches
- 47 + 3 = 50 inches
- 46 + 3 = 49 inches
- 45 + 3 = 48 inches
- 50 + 3 = 53 inches
- 52 + 3 = 55 inches

Step 2: Calculate the sum of the adjusted heights
58 + 55 + 51 + 54 + 50 + 50 + 49 + 48 + 53 + 55 = 533 inches

Step 3: Calculate the number of heights
There are 10 heights given.

Step 4: Calculate the mean height
Mean Height = Sum of Heights / Number of Heights
Mean Height = 533 inches / 10
Mean Height = 53.3 inches

Therefore, the mean height is 53.3 inches.

Explanation:

To find the mean height, we first added 3 inches to each of the given heights. This adjustment accounts for the additional 3 inches mentioned in the question.

Then, we calculated the sum of the adjusted heights, which resulted in 533 inches.

Next, we determined the number of heights, which is 10 in this case.

Finally, we divided the sum of the heights by the number of heights to find the mean height.

Hence, the mean height is calculated to be 53.3 inches.
