(Note that high scores indicate good study hab its and attitudes toward learning.) Follow the four-step process.
For knowing who has better study habits and attitudes toward learning we have to find the mean of both the women and men data.
The first step is that we only take first 18 values of both women(X) and men(Y) data, to make them of same length
Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.
Calculating all values:
= 141.0556
= 121.25
Thus, women has better study habit than men. Since Mean of X is larger than Mean of Y.
8.216secs - 1 wheel; 3.652- 1 hood for I toy car with a wheel and hood the total time is 8.216+ 3.652 = 11.868secs let x secs be the total time taken to put a wheel and hood for 42 cars x secs = 42 cars × the total time for one car x secs = 42× 11.868 x secs= 498.456 secs
