Answer:

20%

Step-by-step explanation:

10 pieces

Austin ate 5/10 of the pizza (5 pieces)

5 pieces = 50%

Sharon ate 0.3 of the pizza (3 pieces)

3 pieces = 30%

50+30=80

100-80=20

20% left for Owen

Hey! For this problem, you just have to convert everything into decimals, and then percentages. To convert a decimal into a percentage, just move the decimal point two to the right and add a percent sign! For example:

The amount that Sharon ate is already converted into a decimal. 0.30 as a percentage is 30%, so she ate thirty percent of the pizza!

However, you still need to convert the amount of pizza that Austin ate from a fraction into a decimal. 5/10 is equivalent to 1/2, which is 0.50! Move the decimal point two to the right, and you get 50%.

50% plus 30% is 80%, which means that only 20% of the pizza is left for Owen!

____ [38]

Answer:

48, 55, 56, 68, 74, 78, 83, 85, 99

Mean: 71.77777777777777777..........

Median: 74

Mode: mode is the number seen the most, but there is no repeating values

Range: 51

Step-by-step explanation:

Mean:

add all the values together, and divide by how many values you have, so 646/9= 71.777777777............

Median:

the number in the middle of the sequence

Range:

the difference between the largest and smallest numbers/values.

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 450 gram setting. It

Arturiano [62]

Answer:

Test statistic = -2.25

P-value = 0.0199

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 450 gram

Sample mean, $\bar{x}$ = 441 grams

Sample size, n = 16

Alpha, α = 0.05

Sample variance = 256

$\sigma^2 = 256\\\sigma = \sqrt{256} = 16$

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 450\text{ grams}\\H_A: \mu < 450\text{ grams}$

We use one-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{441 - 450}{\frac{16}{\sqrt{16}} } = -2.25$

Now,

Degree of freedom =

$=n-1 = 16-1=15$

We can calculate the p-value from the table as:

P-value = 0.0199

Conclusion:

Since the p-value is smaller than the significance level we fail to accept the null hypothesis and reject it.

Thus, there is enough evidence to support the claim that the machine is under filling the bags .
