please help and explain number 1 and 2 thanks Solution1 Yes

Solution

1)

Yes, Statistically study is appropriate as observing the maximum speeds for a period of time and finding the utmost speed for which the bridge has to withstand

the populations of interest are average windspeed of a each day , maximum windspeed of each day , direction of wind speed , effect of seasons on windspeed

2)

Yes , statistically study is appropriate and the perfect statistical method for this case is factorial experiments. Finding the length of the root of each group after a certain period and finding the effectiveness of treatment

the populations of interest are group treated with dilute solution and group which is not treated with any solution
