Answer:

69.1

Step-by-step explanation:

<em>Mean height of 14 students = 69.0 inches</em>

<em>Mean = sum of data/number of data</em>

<em>69 = sum of data/14</em>

<em>sum of data = 966</em>

<u>FOR NEW MEAN:</u>

<em>Height of additional student = 70.5</em>

Mean = sum of data/ number of data

Mean = 966+70.5/14+1

Mean = 1036.5/15

Mean = 69.1

Therefore, the mean height of the 15 students in the class is 69.1
