Answer:

84

Step-by-step explanation:

Sample size = 84 and standard deviation = 4

This means number of people can be 84 +- 4 or 80 to 88

Let the number of meal be X. 

probability of having more people than meals is 5%

Z score = X-mean/ sigma = (X - 84)/4 = 5% of X  = X/5 

5X -84 = 4X 

X = 84
