Times for a surgical procedure are normally distributed. There are two methods. Method A has a mean of 33 minutes and a standard

lilavasa [31]

Answer:

Method A.

Step-by-step explanation:

For solving this question we need to find out the z-scores for both methods,

Since, the z-score formula is,

$z=\frac{x-\mu}{\sigma}$

Where, $\mu$ is mean,

$\sigma$ is standard deviation,

Given,

For method A,

$\mu = 33$

$\sigma=8$

Thus, the z score for 34 is,

$z_1=\frac{34-33}{8}=0.125$

While, for method B,

$\mu = 37$

$\sigma = 4$

Thus, the z score for 34 is,

$z_2=\frac{34-37}{4}=-0.75$ ,

Since, $z_1 > z_2$

Hence, method A is preferred if the procedure must be completed within 34 minutes.

Using the given set of numbers find the mean (rounded to the nearest tenth), median,mode and range: 18,19,16,18,14,17,18 and 15

sashaice [31]

Answer:

Mean = 16.9
Mode = 18
Median = 17.5

Step-by-step explanation:

Given data:

18, 19, 16, 18, 14, 17, 18, 15

The data in the ascending order:

14, 15, 16, 17, 18, 18, 18, 19

The mean:

(14 + 15 + 16 + 17 + 18*3 + 19)/8 = 16.9 (rounded)

The median:

(17 + 18)/2 = 17.5 (the average of middle terms)

The mode:

18 (the most repeated number)
