First straight in the middle second diagonal
Answer: NO.
Step-by-step explanation:
As per given , we have to test the hypothesis.

∵
is two-tailed , so our test is a two-tailed test.
Also, the standard deviation is known to be 0.8 , so we use z-test.
Test statistic:
, where
= Sample mean
= population mean
= Population standard deviation
n= Sample size
Put
n= 110 , we get

P-value for two tailed test = 2P(Z>|z|)
= 2P(Z>|1.31|) = 2(1-P(Z<1.31)) [∵ P(Z>z)=1-P(Z<z)]
=2(1- 0.9049) [By z-table]
=0.1902
Decision : ∵ P-value (0.1902) > Significance level (0.02).
It means we do not reject the null hypothesis.
[When P-values < Significance level then we reject the null hypothesis.]
Conclusion : We do not have sufficient evidence at the 0.02 level that the valve does not perform to the specifications.
3/4
1/6 of the pot is 2/12
1/12 + 2/12 is 3/12
1 - 3/12 is 9/12 = 3/4
3/4 of the pot is left over
Answer:
18
Step-by-step explanation:
Equation
2x=36
Solve
x=18
132/2 = 66
66/2 = 33
33/3 = 11
11/11 = 1
132 = 2^2 * 3 * 11
55121/11 = 5011
5011/5011 = 1
55,121 = 11 * 5011
LCM = common factor with larger exponent * not common factors
LCM = 2^2 * 3 * 11 * 5011
LCM = 661,452
