A physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She randomly selected 54 men and 70 women to participate in the study. Each subject was required to step up and down a 6-inch platform. The pulse of each subject was then recorded. The following results were obtained.

If you perform FFT on 20 seconds of data with no averaging, what are the first 3 values of the corresponding frequency vector in Hz?
A sample of 15 participants took part in a hearing experiment. Among other things, the absolute hearing threshold (in decibels) was measured for each participant. The 15 measurements were as follows. 25,22,18,35,37,34,31,39,39,39,36,36,33,33 30 Draw the histogram for these data using an initial class boundary of 17.5, an ending class boundary of 45.5, and 4 classes of equal width.
A sample of 17 participants took part in a hearing experiment. Among other things, the absolute hearing threshold (in decibels) was measured for each participant. The 17 measurements were as follows: 25, 22, 18, 35, 37, 34, 31, 36, 36, 36, 33, 33, 30, 30, 30, 26, 26 Send data to calculator Draw the histogram for these data using an initial class boundary of 17.5 and a class width of 4. Note that you can add or remove classes from the figure. Label each class with its endpoints. Frequency 7- 5+ 4+ 2+ 1- Absolute hearing threshold (in decibels) 3.
I hope the solution is to choose the correct one only, no more
