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.

Lara has three cats: Socks, Princess, and Luna. The ratio of Sock's weight to Princess's weight is 4:5. The ratio of Princess's
romanna [79]
A = Sock's weight
b = Princess' weight
c = Luna's weight

a : b = 4 : 5
b : c = 6 : 7

at this point, we have to change the 2 ratios (a : b and b : c) into one ratio (a : b : c)
to do that, we have to change the ratio number so the number b in both ratio is the same

a : b = 4 : 5 = 24 : 30
b : c = 6 : 7 = 30 : 35
From that we can conclude that
a : b : c = 24 : 30 : 35

Since we're looking for the ratio of Sock's weight to Luna's weight, it will be
a : c = 24 : 35

The equation that corresponds to this diagram is 6 (x+ 1)=24.
Annette [7]

Answer:

x is 3

Step-by-step explanation:

6 (x + 1) = 24

6 (x) + 6(1) = 24

6x + 6 = 24

Subtract 6 on both sides

6x + 6 - 6 = 24 - 6

6x + 0 = 18

6x = 18

x = 18/6

x = 3

In attempting to calculate the carrying capacity of a cylindrical pipe, Avery measured the outer diameter to be 2 inches, neglec
andreev551 [17]
Volume of the pipe = πr^2l
Wrong measure = π x (2)^2 x l = 4πl
Correct measure = π x (2 - 2(1/8))^2 x l = 49/16πl
error = 4πl - 49/16πl = 15/16πl

% error = ((15/16πl) / 49/16πl) x 100% = 30.6%
