Answer:
the answer is A
Step-by-step explanation:
48 x 2 = 96
33 x 3 = 99
99 + 96 = 195
Answer:
no
Step-by-step explanation:
exclusive pertains to one, hence the phrase, exclusive.
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 6.8 psi
For the alternative hypothesis,
µ ≠ 6.8
This is a 2 tailed test
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 6.8
x = 6.9
σ = 0.7
n = 140
z = (6.9 - 6.8)/(0.7/√140) = 0.17
Therefore, the value of the test statistic us 0.17
5.2 represented with significant figures. 5.2083 (3 repeating) is the actual answer.
2,2 and 4.5 would be a circle in this point
