Answer:
B. There is not sufficient evidence at the 0.02 level of significance that the new technique reduces training time.
Step-by-step explanation:
We are given that using traditional methods it takes 107 hours to receive an advanced flying license.
A researcher believes the new technique may reduce training time and decides to perform a hypothesis test.
Let 
= <u><em>average training time to receive an advanced flying license</em></u>
So, Null hypothesis, 
: 
107 hours {means that the new technique doesn't reduce training time}
Alternate Hypothesis, 
: < 107 hours {means that the new technique may reduce training time}
Now, it is stated that after performing the test on 50 students, the researcher decides to reject the null hypothesis at a 0.10 level of significance.
As we know that if the test statistics value is rejected at a 10% level of significance, then it must not be rejected at the 0.02 level of significance.
This means that there is not sufficient evidence at the 0.02 level of significance that the new technique reduces training time because our null hypothesis has not been rejected.
Ok, think about it. What’s the definition of a irrational number? Can the number be converted to a fraction or be able to be turned into a decimal that repeats or terminates? If so your looking at a rational number. If it can’t be turned into a fraction or become a repeating or terminating decimal then your number is likely a irrational number. Hope this helps. And your number is a rational number.
The Question is improper it may be pi instead of x.
Answer:
Therefore,
Step-by-step explanation:
Convert 5x/12 to degrees.
So it may be
To Convert 
into degrees.
Solution:
It is the measure of an angle in Radians.
So to Convert Radian to Degree we need to multiply the radian angle by
So we will get the measure angle in Degree now.
∴ 
We pi will get cancelled will get
∴ 
Therefore,
Answer:
no
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Use PEDMAS
18 - 6(2+4-1+2) ÷ 3
18 - 6(6 - 1 + 2) ÷ 3
18 - 6(5 + 2) ÷ 3
18 - 6(7) ÷ 3
18 - 42 ÷ 3
18 - 14
4
Hope this helps!
