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:

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

Find the value of the expression: a. 3x^0 for x=2.6, b. 10a^2b^0 for a=–3, b=–8

nekit [7.7K]

Step-by-step explanation:

For x = 2,6

$= 3{x}^{0}$

$= 3 \times {2,6}^{0}$

$= 3 \times1$

$= 3$

$\:$

For a = -3 and b = -8

$= 10 \times {a}^{2} \times {b}^{0}$

$= 10 \times {( - 3)}^{2} \times {( - 8)}^{0}$

$= 10 \times 9 \times 1$

$= 90$

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of mon

nirvana33 [79]

(420,104)(720,164)
slope = (164 - 104) / (720 - 420) = 60/300 = 1/5

y = mx + b
slope(m) = 1/5
(420,104)...x = 420 and y = 104
now we sub and find b, the y int
104 = 1/5(420) + b
104 = 84 + b
104 - 84 = b
20 = b

so ur equation is : y = 1/5x + 20
