\sf{Slope =\frac{y_2-y_1}{x_2-x_1}}\\\\5 = \frac{y - 6}{21-5} \\\\5=\frac{y-6}{16}\\\\16(5) = y-6\\\\80 = y-6\\\\y = 80 + 6\\\\\boxed{\bf{y=86}}

If slope is 5, 5.(x-5)=y-6 so 5x-y-19=0. When x=21, y=86.

a normal distribution with a mean of 25 minutes with a population standard deviation of 5 minutes. The store manager sampled 100
sergiy2304 [10]

Answer:

z=\frac{24.25-25}{\frac{5}{\sqrt{100}}}=-1.5      

The p value for this case would be given with this probability:

p_v =P(z  

For this case since the p value is higher than the significance level of 0.01 we have enough evidence to fail to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is significantly less than 25 min.

Step-by-step explanation:

Information given

\bar X=242.5 represent the sample mean      

\sigma=5 represent the population deviation

n=100 sample size      

\mu_o =25 represent the value to check

\alpha=0.01 represent the significance level

z would represent the statistic  

p_v represent the p value

Hypotheis to test

We want to verify if the true mean is less than 25 min, the system of hypothesis would be:      

Null hypothesis:\mu \geq 25      

Alternative hypothesis:\mu < 25      

The statistic would be given by:

z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}} (1)      

And replacing the info given we got:

z=\frac{24.25-25}{\frac{5}{\sqrt{100}}}=-1.5      

The p value for this case would be given with this probability:

p_v =P(z  

For this case since the p value is higher than the significance level of 0.01 we have enough evidence to fail to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is significantly less than 25 min.

Step-by-step explanation:

If you solve the second equation and substiture to the first, you get y = 5, and x = -7.
