Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.
Step-by-step explanation:
Definitions:
- Null hypothesis
is a statement describing population parameters according to the objective of the study. It takes "≤,≥,=" signs.
- Alternative hypothesis
is a statement opposite to the null hypothesis elaborating population parameters according to the objective of the study. It takes ">, <, ≠" signs.
Given: The diameter of a spindle in a small motor is supposed to be 5.8 millimeters.
If the spindle is either too small or too large, the motor will not work properly. so, Mean diameter ≠ 5.8 to work correctly.
i.e. ![H_a: \text{Mean}\neq 5.8](https://tex.z-dn.net/?f=H_a%3A%20%5Ctext%7BMean%7D%5Cneq%205.8)
So, ![H_a: \text{Mean =5.8}](https://tex.z-dn.net/?f=H_a%3A%20%5Ctext%7BMean%20%3D5.8%7D)
The required null and alternative hypotheses:
H0: Mean= 5 and Ha: Mean is not equal to 5.

Answer:
%0.13
Step-by-step explanation:
10 quarters= $2.5 which is 25 dimes
10 nickels= $0.5 which is 5 dimes
10 dimes= $100
100+25+5= 130 dimes = $13
13/100 = %0.13
