Your medical research team is investigating the standard deviation of the cost of a 30-day-supply of a certain heart medication.

Valentin [98]

Considering the situation described, the hypothesis tested are given as follows:

The null hypothesis is $H_0: \sigma \geq 23$

The alternative hypothesis is $H_1: \sigma < 23$

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:

$H_0: \sigma \geq 23$

At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

$H_1: \sigma < 23$

F(x)=6x-3 graph the function in inverse

Digiron [165]

Answer:

See attachment.

Step-by-step explanation:

f(x) = 6x - 3

y = 6x - 2

Switch out x for y.

x = 6y - 2

Solve for y.

x + 2 = 6y

$\frac{x+2}{6}$ = y

Graph.
