Answer:
Mean of these n = 23 observations is 16.21 .
Step-by-step explanation:
We are given with the one‑sample t statistic from a sample of n = 23 observations for the two‑sided test of H0 : μ = 15 versus Hα : μ > 15 has the value t = 2.24 . Also, the standard deviation from the sample is 2.4.
So, Null Hypothesis, : = 15
Alternate Hypothesis, : > 15
The test statistics that is used here is One sample t-test statistics;
T.S. = ~
where, = sample mean
= population mean = 15
s = sample standard deviation = 2.4
n = sample size = 23
So, test statistics = ~
2.24 =
1.21 = - 15
= 1.21 + 15 = 16.21
Therefore, mean of n = 23 observations is 16.21 .
Answer:
21.25 inches is the width
Step-by-step explanation:
27.5/11 = 2.5 means that the projected image is 2.5 times bigger than the transparency so 8.5*2.5 is 21.25
The two numbers that would multiply to equal the value on top and add to the value on the bottom would be -2 and 9.
-2 x 9 = 18
-2 + 9 = 7
Answer:
Step-by-step explanation:
11c-12-2c=6
Combine like terms:
9c-12=6
+12 +12
9c= 18
c= 2
