Answer:
Value of test statistics = 2.30
Step-by-step explanation:
We are given that for a sample of 35 items from a population for which the standard deviation is 20.5, the sample mean is 458.
Also, Null Hypothesis, 
: 
= 450
Alternate Hypothesis, 
: 
450
The test statistics that will be used here is One sample t-test statistics;
T.S. = 
~ 
where, 
= sample mean = 458
s = sample standard deviation = 20.5
n = sample of items = 35
So, test statistics = 
~ 
= 2.30
Therefore, the value of test statistics is 2.30 .
7/9 = 0.777777
8/11 = 0.727272
0.79
84% = 0.84
4/5 = 0.8
8/11, 7/9, 0.79, 4/5, 84%

Answer:
a in this equation would be 3/4 because...
Step-by-step explanation:
2/3a−1/6=1/3
2/3a+−1/6=1/3
2/3a+−1/6+1/6=1/3+1/6
2/3a=1/2
Multiply both sides by 3/2.
(3/2)*(2/3a)=(3/2)*(1/2)
a=3/4
Hope this helps!
