Answer:
-0.5
or
-3.5
Step-by-step explanation:
15.5/1.25 = 12.4 pieces
We can't have .4 of a piece if they are all to be equal so we can obtain 12 pieces of ribbon in total.
Answer:

Step-by-step explanation:
7,491 times 19 yields 142, 329
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 .
