What is the volume of the prism below?

death valley located in the United States is 282 feet below sea level is the level of Galilee located in Israel is 682 feet be

umka21 [38]

Answer:

400 feet.

Explanation:

We need to find the difference between the lowest point of Galilee and the lowest point of Death Valley. We can find this by subtracting the lowest point of Galilee by the lowest point of Death Valley. It says the lowest point of Galilee is 682 feet below sea level and the lowest point of Death Valley is 282 feet below sea level. Therefore, we subtract 682 - 282, which equals 400.

A machine in the student lounge dispenses coffee. The average cup of coffee is supposed to contain 7.0 ounces. A random sample o

Elenna [48]

Answer:

$t=\frac{7.4-7}{\frac{0.7}{\sqrt{7}}}=1.512$

The degrees of freedom are

$df=n-1=7-1=6$

And the p value for this case is:

$p_v =2*P(t_{(6)}>1.512)=0.181$

The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.

Step-by-step explanation:

Information provided

$\bar X=7.4$ represent the sample mean

$s=0.7$ represent the sample standard deviation

$n=7$ sample size

$\mu_o 7$ represent the value to verify

t would represent the statistic

$p_v$ represent the p value

System of hypothesis

We want to verify if the average amount of coffee per cup is different from 7 ounces, the system of hypothesis would be:

Null hypothesis: $\mu = 7$

Alternative hypothesis: $\mu \neq 7$

The statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Replacing the info given we got:

$t=\frac{7.4-7}{\frac{0.7}{\sqrt{7}}}=1.512$

The degrees of freedom are

$df=n-1=7-1=6$

And the p value for this case is:

$p_v =2*P(t_{(6)}>1.512)=0.181$

The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.
