Black perch are ocean fish found on reefs near shore. a graduate student at csulb is interested in testing whether black perch from two different populations behave differently, on average. in her experiment, she measured routine swimming velocity (to the nearest 0.001 cm/s) for 18 fish from one population, and 21 fish from another. a) which statistical test would you use to analyze these data?

The graph of f(x)=|x| is reflected over the y-axis and horizontally compressed by a factor of 1/9. write a formula for function g(x)

How do i do this activity, is appreciated

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so,about which interval is it approximately symmetric?
