1 day = 225 liters
2 days = 450 liters

I don't think it is proportional..

Proportional is like..
1 day = 12 bags of rice
2 days = 11 bags of rice
3 days = 10 bags of rice

Thanks.

Fluoxetine, a generic anti-depressant, claims to have, on average, at least 20 milligrams of active ingredient. An independent l

san4es73 [151]

Answer:

$t=\frac{18.7-20}{\frac{5}{\sqrt{80}}}=-2.326$

$df=n-1=80-1=79$

$p_v =P(t_{(79)}$

Step-by-step explanation:

Information given

$\bar X=18.7$ represent the sample mean for the content of active ingredient

$s=5$ represent the sample standard deviation for the sample

$n=80$ sample size

$\mu_o =20$ represent the value that we want to test

t would represent the statistic

$p_v$ represent the p value for the test

System of hypothesis

We need to conduct a hypothesis in order to check if the true mean for the active agent is at least 20 mg, the system of hypothesis would be:

Null hypothesis: $\mu \geq 20$

Alternative hypothesis: $\mu < 20$

The statistic would be:

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

Now we can calculate the statistic:

$t=\frac{18.7-20}{\frac{5}{\sqrt{80}}}=-2.326$

P value

The degrees of freedom are calculated like this:

$df=n-1=80-1=79$

Since is a one left tailed test the p value would be:

$p_v =P(t_{(79)}$

If I saved up $10 every 2 weeks, how much would I have saved in a year? Please help, thank you!

I believe there’s 52 weeks in a year besides leap year so it would be 52 divided by 2 times 10 and you’d have your answer
