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 .
-6p - 3 = 9, Solve for p
Add 3 to both sides.
-6p = 12
Divide -6 by both sides.
p = -2
Answer:
3.9, 4.01, 4.02, 4.03, 4.06, 4.08
Step-by-step explanation:
math
(-2,4)
2(1/2x+5)+5x=-2
x=-2
plug it back into and equation
y=1/2*-2+5
y=4
5.5lbs(16oz/lb)+3lbs(16oz/lb)+6oz=142 oz or if you prefer
142oz(lb/16oz)=8 0lb+0.875 lb(16oz/lb)=8 lb, 14oz
