We have the mean, μ = 20 and the standard deviation, σ = 4
X ≈ N(20, 4²)
We want P(X<15)
Standardising gives
P(X<15) = P(Z<
)
P(X<15) = P(Z< -1.25) ⇒ When the value of the z-score is negative, we will read the value of z<1.25 on the z-table then subtract the answer from 1
P(X<15) = 1 - P(Z<1.25)
P(X<15) = 1 - 0.8944
P(X<15) = 0.1056
Hence, the probability that pizza takes less than 15 minutes to be delivered is 0.1056 = 10.56%

Answer: Medians, Less
Part A
Use the measures of center from the box plots to make an inference about the data. Use the drop-down menus to explain your answer.
Based on the <u><em>medians</em></u>, the plants in Group A grew
<em><u>less</u></em><em><u> </u></em>on average, as compared to the plants in Group B.
Part B Answer: Greater, Less
The range and IQR are <u>greater</u>
in Group B as compared to Group A, so there is <u>less</u> variability in the growth of plants in Group B.
