The answer is -1.01
I first changed the signs of the ones i could. So <span>-0.75+(2/50)+0.4(-3/4)
Then i multiplied the 0.4*-3/4 which equals -0.3
So you are left with </span><span>-0.75+(2/50)-0.3
2/50 is equal to 0.04 so now it is </span> -0.75+0.04-0.3 and the rest is simple math. Which equals -1.01

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:

$H_1: \sigma < 23$
