The average high-density lipoprotein (HDL) cholesterol level of adult females is 53 milligrams per deciliter. You want to determ

emmasim [6.3K]

Answer:

$t=\frac{54.1-53}{\frac{1.78}{\sqrt{12}}}=2.14$

$df = n-1= 12-1=11$

$p_v = P(t_{11}>2.14) =0.0278$

Step-by-step explanation:

Data provided

$\bar X=54.1$ represent the sample mean in mg per deciliter of cholesterol level

$s=1.78$ represent the sample standard deviation

$n=12$ sample size

$\mu_o =53$ represent the value that we want to test

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

System of hypothesis

We need to conduct a hypothesis in order to check if the mean is higher than 53 mg per deciliter, the system of hypothesis would be:

Null hypothesis: $\mu \leq 53$

Alternative hypothesis: $\mu > 53$

The statistic is given by:

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

Calculate the statistic

Replacing into the formula we got:

$t=\frac{54.1-53}{\frac{1.78}{\sqrt{12}}}=2.14$

P-value

We need to find first the degrees of freedom:

$df = n-1= 12-1=11$

The p value for this case since we have a right tailed test is:

$p_v = P(t_{11}>2.14) =0.0278$

Neal buys a board game. He pays for the board game and pays \$1.54$1.54dollar sign, 1, point, 54 in sales tax. The sales tax rat

jok3333 [9.3K]

You provide info on the circumstances but do not provide instructions. What are you looking for here?

Suppose the board game cost $25 before tax.

If the tax payable was $1.54, then the sales tax rate was r:
$1.54
$25r = $1.54. Solving for r, r = ---------- = 0.0616, or 6.16%
$25

If this isn't quite what you were looking / hoping for, then please ensure you have copied down the original problem exactly.
