how do you construct a frequency histogram?

Chuck has noticed over the last several years that as he gets older, he also gets more politically conservative. What is the correlation between his age and his conservative leanings?Positive Negative Impossible to Determine ( don't hand writing solution)

I use excel. I do not know what data anlysis toolpak to use, however, to find the answer, t stat, df, P, etc. I also don't know how to word Ho and Ha. Thanks!   The data shown below are the initial weights and gains in weight (in grams) of female rats on a high protein diet from 24 to 84 days of age. The point of interest in these data is whether the gain in weight is related to (dependent on) the initial weight. If so, then feeding experiments on female rats can be made more precise by adjusting for differences in initial weights of the rats. Statistically test this with a regression analysis.   Rat Number Initial Weight (gms) Weight Gain (gms) 1 50 128 2 64 159 3 76 158 4 64 119 5 74 133 6 60 112 7 69 96 8 68 126 9 56 132 10 48 118 11 57 107 12 59 106 13 46 82 14 45 103 15 65 104   What is the equation for the multiple regression? What is the best estimate of the amount of variance in Y which is due to its regression on the independent variables?

PLEASE SHOW AN EXPLANATION FOR EACH PART

Which scatter plot shown has the strongest negative correlation?

Correlation does not imply causation. What does this mean? Find an example in the media that needs to understand this concept and explain it to your peers. Be sure to include the link to the example you are using.

Letter (d) Would i be wrong if i said yes the data set consisting of the annual salary for each employee at the MNM company is a population since no employee salary is excluded from the data

can you show me what a symmetric histogram would like like

What is the median?
