Solution :
Here we can use the Binomial distribution, as there are only two possible outcomes.
The given data:
n = 150
q = 98%
= 0.98
p = probability of not finding relief = 1 - 0.98
= 0.02
A). The number of the individuals who do not find any relief from sinusitis is :
E(x) = np
= 150 x 0.02
= 3
B). The uncertainty of my estimate is = 

= 1.716
2. no number is associated with it
qualitative describes the appearance of sth like it's blue
3+3+3+4+4+5+6+6+7+9+9=59
59/11=5.36
so your mean is 5.36
