Answer:
The mean launch temperature for flights with O-ring damage is significantly lesser than Flights with No O-ring
Step-by-step explanation:
Let
Null hypothesis : H0 : μ1 ≥ μ2
Alternate hypothesis : Ha : μ1 < μ2
next calculate the test statistic
t = -2.312
calculate the P-value
p-value = T.DIST ( t ,df ) ( excel function )
= 0.0270
Given that P-value ( 0.020 ) < level of significance ( 0.05 ) we will not fail to reject the null hypothesis
Attached below is the detailed solution
Answer: x = 9
Step-by-step explanation:
1) Combine multiplied terms into a single fraction
2) Find a common denominator
3) Combine fractions with common denominator
4) Multiply from left to right (PEMDAS)
5) Multiply all terms by the same value to eliminate fraction denominators
6) Cancel multiplied terms that are in the denominator
7) Multiply again
8) Add _ to both sides
9) Divide both sides by the same factor getting 125x/125 = 1125/125
10) Simplify, x = 9
Answer:
