The diameter of a spindle in a small motor is supposed to be 5.8 millimeters (mm) with a standard deviation of 0.14 mm. If the s
Citrus2011 [14]

Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.

Step-by-step explanation:

Definitions:

  • Null hypothesis (H_0) is a statement describing population parameters according to the objective of the study. It takes "≤,≥,=" signs.  
  • Alternative hypothesis(H_a)  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

So, H_a: \text{Mean =5.8}

The required null and alternative hypotheses:

H0: Mean= 5 and Ha: Mean is not equal to 5.
