Answer:

The answer is below

Explanation:

1) The synchronous speed of an induction motor is the speed of the magnetic field of the stator. It is given by:

\(n_s=\frac{120f_s}{p}\\ Where\ p\ is \ the \ number\ of\ machine\ pole, f_s\ is\ the\ supply \ frequency\\and\ n_s\ is \ the \ synchronous\ speed(speed \ of\ stator\ magnetic \ field)\\Given: f_s=60\ Hz, p=4. Therefore\\\\n_s=\frac{120*60}{4}=1800\ rpm\)

2) The speed of the rotor is the motor speed. The slip is given by:

\(Slip=\frac{n_s-n_m}{n_s}. \\ n_m\ is\ the \ motor\ speed(rotor\ speed)\\Slip = 0.05, n_s= 1800\ rpm\\ \\0.05=\frac{1800-n_m}{1800}\\\\ 1800-n_m=90\\\\n_m=1800-90=1710\ rpm\)

3) The frequency of the rotor is given as:

\(f_r=slip*f_s\\f_r=0.04*60=2.4\ Hz\)

4) At standstill, the speed of the motor is 0, therefore the slip is 1.

The frequency of the rotor is given as:

\(f_r=slip*f_s\\f_r=1*60=60\ Hz\)

The level of measurement for the given data is as follows:

(a) Temperature - Quantitative, interval

(b) Allergies - Qualitative, nominal

(c) Weight - Quantitative, ratio

(d) Pain level - Quantitative, ordinal

Temperature is a quantitative variable that can be measured on an interval scale because the differences between temperature values are meaningful (e.g., the difference between 20 and 30 degrees Celsius is the same as the difference between 30 and 40 degrees Celsius).

Allergies, on the other hand, are a qualitative variable that can be categorized into different groups or levels without any inherent numerical value. It is measured on a nominal scale, which means there is no numerical order or ranking associated with the categories.

Weight is a quantitative variable that can be measured on a ratio scale. It has a meaningful zero point (absence of weight) and the ratios between weight values are meaningful (e.g., 100 pounds is twice as heavy as 50 pounds).

Pain level is also a quantitative variable, but it is measured on an ordinal scale. The scale of 0 to 10 represents different levels of pain intensity, but the differences between the numbers may not be equal or meaningful. It only provides a ranking or order of pain levels.
