The critical value is used to compute the margin of error. (Margin of error = Critical value x Standard deviation of the statistic or <span>Margin of error = Critical value x Standard error of the statistic).
If the statistic has normal sampling distribution, then the t</span><span>he critical value can be expressed as a </span>t score<span> or as a </span>z score<span>.
</span><span>α = 1 - (confidence level / 100)
</span><span>α = 1 - (93 / 100)=1-0.93=0.07
</span>The critical probability is: <span>pc= 1 - α/2 pc=1-0.035=0.965
The critical value is 1.81.</span>
Answer: D
Step-by-step explanation:
(5) = 4(6) - 19
5= 24-19
5= 5
TRUE
(5) = -3(6) + 23
5 = -18 + 23
5=5
TRUE

The number of messages sent by Elsa, Ryan and Jim are 11 , 84 and 21 respectively.
<em><u>Explanation</u></em>
Suppose, the number of messages Jim sent is 
As Ryan sent 4 times as many messages as Jim, so the number of messages sent by Ryan 
Also, Elsa sent 10 fewer messages than Jim, so the number of messages sent by Elsa 
Given that, they sent a <u>total of 116</u> text messages. So the equation will be.......

So, the number of messages sent by each of them.....

You could do 6*6, which would be 36.
36, which you then divide by 7, the denominator.
5 and 1/7 is the answer.
