The null hypothesis is
The alternate hypothesis is
Step-by-step explanation:
The diameter of a spindle in a small motor is supposed to be 4.1 millimeters

If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 41 spindles to determine whether the mean diameter has moved away from the required measurement.
Tests if it has moved away, that is, if the mean is different from the specified value of 4.1. So the alternate hypothesis is
Answer:
6080 cm OR 60.8m
Step-by-step explanation:
75 x 40 = 3000 cm
77 x 40 = 3080 cm

3000 + 3080 = 6080 cm = 60.8m
<span>Pablo made $323 for 17 hours of work at the same rate how many hours would he have to work to make $95.
Hourly rate = $323/17=$19
Number of hours required to make $95
=$95/($19/hour)
=5 hours.</span>
Convert the two fractions to decimals
Hope this helps!
