X=90y=70I used the process of elimination.
Answer:
H0: u ≥ 9.5
Ha: u < 9.5
Step-by-step explanation:
The null hypothesis and the alternate hypothesis are reverse of each other.
The claim is either set as the null or alternate hypothesis
The null hypothesis is : H0: u ≥ 9.5 the mean breaking strength of a ceramic insulator is at least 9.5 which is considered equivalent to the standard.
The alternate hypothesis is: Ha: u < 9.5 the mean breaking strength of a ceramic insulator is less than 9.5 which is not considered equivalent to the standard.
The two numbers are 3 and 5, because 3 is the product of 3(1) = 1, and 3(5) = 15. Which is divisible by 5. Both 3 and 5 are less than 10.
R = 14.1
Explanation:
r - 17.3 = -3.2
r = - 3.2 + 17.3
r = 14.1
