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 = $\sqrt{npq}$

                                                              $=\sqrt{150 \times 0.02 \times 0.98}$

                                                              = 1.716

What is the equation of the line, written in slope-intercept form? Show how you determined the equation.
kondor19780726 [428]
The equation of a line is defined by: y=mx+b

Step 1: Find the slope (rise over run) so, the rise is 15.7 and the run is 6. 15.7/6=2.62

y=2.62x+b

Step 2: Find the b value (y intercept) - this is where the line goes through the y axis. In this case, it's 15.7

Step 3: add the slope and the b value together - y=2.62x+15.7
