Answer:
96 Servings
Step-by-step explanation:
Divide the total 72 cups by the serving, 0.75 cup, which equals 96 servings
Answer:
21.759
Step-by-step explanation:
Given that :
Mean (m) = 25
Standard deviation (s) = 12.5
Sample size (n) = 40
α = 90%
The confidence interval is obtained using the relation:
Mean ± Zcritical * s/sqrt(n)
Zcritical at 90% confidence interval = 1.64
25 ± 1.64 * (12.5/sqrt(40))
Lower boundary : 25 - 1.64(1.9764235) = 21.75866546
Upper boundary : 25 + 1.64(1.9764235) = 28.24133454
(21.759, 28.241)
Hence, lower bound of confidence interval is : 21.759
Answer:
73/5
Step-by-step explanation:
Answer:
The equation would be y = 1/2x + 5
Step-by-step explanation:
To find this equation, we start by using point slope form, and then plugging the slope in for m and the point in at (x1, y1).
y - y1 = m(x - x1)
y - 7 = 1/2(x - 4)
And now we solve for y.
y - 7 = 1/2(x - 4)
y - 7 = 1/2x - 2
y = 1/2x + 5
Given that the summary of the population is:
<span>Mean: 42
Median: 38
Range: 52
Mean Deviation: 11.23
To obtain the sample that is closest to the mean we shall proceed as follows:
Shift 1:
</span><span>18,25,56,42,29,38,54,47,35,30
The mean of the sample is:
(18+25+56+42+29+38+54+47+35+30)/10
=374/10
=37.4
Shift 2:
</span><span>23, 19, 50, 49, 67,34,30,59,40, 33
</span>The mean is:
(23+19+50+49+67+34+30+59+40+33)/10
=404/10
=40.4
Shift 3:
<span>Shift 3
19, 22, 24, 40, 45, 29, 33, 29, 39, 59
The mean of the values
</span>(19+22+24+40+45+29+33+29+39+59)/10
=339/10
=33.9
Shift 4:
<span>21, 23, 25, 40, 35, 19, 70, 40, 22, 23
The mean of the values is:
(</span>21+23+25+40+35+19+70+40+22+23)/10
=318/10
=31.8
From the calculations, the sample that has mean that is close to population mean is Shift 2
