Answer:

The distribution is negatively (left) skewed

Step-by-step explanation:

Notice how most of the data is clustered on the right side of the distribution and there's more spread in the left side of the data, meaning the left tail is longer. This creates a negative skew in the data. Review the attached diagram to learn more.

Answer:

total cost = 351.33

Step-by-step explanation:

The tax is found by multiply the cost times the tax rate

tax = 334.60 * .05

tax =16.73

Add the tax to the cost of the item to get the total cost

total cost = 16.73 + 334.60

total cost = 351.33

A 34-inch piece of wood is 2.4% of a longer piece of wood. How long is the longer piece of wood? Show your work. You can use pro
riadik2000 [5.3K]
Think of this as a proportion: 2.4 is to 100, as 34 is to L ("L" for "Long piece.")

Cross multiply to get 2.4 L = 3400, then divide both sides by 2.4 to be left with

L = 3400/2.4, so

L = 1416.666...

So the longer piece of wood is 1,416.66... inches long.

Hope this helps!!:)

One measure of an athlete’s ability is the height of his or her vertical leap. Many professional basketball players are known fo

Answer:

(1) P(\bar X < 26 inches) = 0.0436

(2) P(27.5 inches < \bar X < 28.5 inches) = 0.2812

Step-by-step explanation:

We are given that the mean vertical leap of all NBA players is 28 inches. Suppose the standard deviation is 7 inches and 36 NBA players are selected at random.

Firstly, Let \bar X = mean vertical leap for the 36 players

Assuming the data follows normal distribution; so the z score probability distribution for sample mean is given by;

            Z = \frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } } ~ N(0,1)

where, \mu = population mean vertical  leap = 28 inches

            \sigma = standard deviation = 7 inches

            n = sample of NBA player = 36

(1) Probability that the mean vertical leap for the 36 players will be less than 26 inches is given by = P(\bar X < 26 inches)

   P(\bar X < 26) = P( \frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } } < \frac{26-28}{\frac{7}{\sqrt{36} } } ) = P(Z < -1.71) = 1 - P(Z \leq 1.71)

                                                 = 1 - 0.95637 = 0.0436

(2) <em>Now, here sample of NBA players is 26 so n = 26.</em>

Probability that the mean vertical leap for the 26 players will be between 27.5 and 28.5 inches is given by = P(27.5 inches < \bar X < 28.5 inches) = P(\bar X < 28.5 inches) - P(\bar X \leq 27.5 inches)

    P(\bar X < 28.5) = P( \frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } } < \frac{28.5-28}{\frac{7}{\sqrt{26} } } ) = P(Z < 0.36) = 0.64058 {using z table}                      

    P(\bar X \leq 27.5) = P( \frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } } \leq \frac{27.5-28}{\frac{7}{\sqrt{26} } } ) = P(Z \leq -0.36) = 1 - P(Z < 0.36)

                                                        = 1 - 0.64058 = 0.35942

Therefore, P(27.5 inches < \bar X < 28.5 inches) = 0.64058 - 0.35942 = 0.2812
