If f(x) = (5x^3 - 4)^4, then what is f '(x)?

vlabodo [156]

You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:

4*(5x^3-4)^3 * 3*5x^2 =

60x^2 (5x^3-4)^3

H 0 : μ ≥ 25 H 1 : μ < 25 Your sample consists of 28 subjects, with a mean of 23.2 and standard deviation of 8.6. Calculate t

kykrilka [37]

Answer:

The test statistic would be given by:

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

And replacing we got:

$t=\frac{23.2-25}{\frac{8.6}{\sqrt{28}}}=-1.11$

Step-by-step explanation:

Information given

$\bar X=23.6$ represent the sample mean

$s=8.6$ represent the sample standard deviation

$n=28$ sample size

$\mu_o =25$ represent the value that we want to test

t would represent the statistic

System of hypothesis

We want to test if the true mean is lower than 25, the system of hypothesis would be:

Null hypothesis: $\mu \geq 25$

Alternative hypothesis: $\mu < 25$

The test statistic would be given by:

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

And replacing we got:

$t=\frac{23.2-25}{\frac{8.6}{\sqrt{28}}}=-1.11$
