Historical data for a local steel manufacturing company shows that the average number of defects per standard sheet of steel is

Yanka [14]

Answer:

Therefore the correct answer is A.) 84.88%

Step-by-step explanation:

i) λ = 2

ii) λ for three units = 2 $\times$ 3 = 6

iii) P(x ≥ 4) = 1 - P(x < 4) = 1 - {P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) }

= 1 - { $\frac{e^{-6}6^{0} }{ 0!} + \frac{e^{-6}6^{1} }{ 1!} + \frac{e^{-6}6^{2} }{ 2!} + \frac{e^{-6}6^{3} }{ 3!}$ }

= 1 - (0.0025 + 0.0149 + 0.0446 + 0.0892)

= 0.8488

Therefore the correct answer is A.) 84.88%

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.

ICE Princess25 [194]

Answer:

The weights within this range are:

8.9

9.5

9.8

10.4

Step-by-step explanation:

The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:

9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)

8.5 ≤ x ≤ 10.5

uppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5

Marizza181 [45]

Answer:

$P(x \le 3.24) = 0.97725$

Step-by-step explanation:

Given

$\bar x = 2.5$

$\sigma = 0.37$

Required

Percentage that is not more than 3.24

The above implies that:

$x = 3.24$

Calculate z score

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

$z = \frac{3.24 - 2.5}{0.37}$

$z = \frac{0.74}{0.37}$

$z = 2$

So, the probability is represented s:

$P(x \le 3.24) = P(z \le 2)$

From z probability

$P(z \le 2) = 0.97725$

Hence:

$P(x \le 3.24) = 0.97725$
