The number of calories burned at the gym is normally distributed with a mean of 425 and a standard deviation of 51. Find the Z-s
Galina-37 [17]

Answer:

(a) -3.708

(b) 1.706

(c) 0.490

Step-by-step explanation:

The z-score of normal distribution is given as:

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

(a)

Given:

Score is, x=268

Mean value is, \mu =425

Standard deviation is, \sigma = 51

z-score is, z=\frac{268-425}{51}=\frac{-157}{51}=-3.078

(b)

Given:

Score is, x=512

Mean value is, \mu =425

Standard deviation is, \sigma = 51

z-score is, z=\frac{512-425}{51}=\frac{87}{51}=1.706

(c)

Given:

Score is, x=450

Mean value is, \mu =425

Standard deviation is, \sigma = 51

z-score is, z=\frac{450-425}{51}=\frac{25}{51}=0.490

Sergeu [11.5K]

Part B: 200 is the total number of teenagers that Damian surveyed.

Part C: Polly surveyed 850 teenagers to find out their favorite type of music. She found that 132% of the teenagers surveyed like hard rock.

Step-by-step explanation:

Part A: % = 1/100, 32% = 32/100, so 32% of 850 is

32/100 x 850 = 272.

Part B: if Total is T, then 75% of T is = 150, i.e,

75/100 x T = 150, making T subject of relation, then T, Total = 200.
