Is the mass of the lead 3.4 x 10^(-22) or literally 3.4 x 10 - 22 or just 22g? The problem has given you volume and density. D = mass/ volume You're trying to find mass, so your equation's going to be m= dv m= 15. 82 g Divide this by whatever your mass was, either 3.4 ...
Statistics
True or False 1. Chi square tests of independence and homogeneity are both usually right-tailed tests. 2. A chi square goodness-of-fit test is appropriate for determining whether a random number generator is truly random.

A fair 20-sided die is rolled 60 times, and the value of chi-square is computed using expected counts of 3 for each face. If this process is repeated many times, the shape of the distribution of the values of chi-square should be... A uniform B bimodal C skewed left D skewed r...

It really just depends. It could be a lot of differen things: 4/2, 6/3, 8/4, e.t.c It just depends on what you want to make it compatible with. For example, say you had 2 + (7/8). You would need to put that 2 into a fraction with a denominator of 8. You would multiply 2 by 8 a...

Suppose you have a chi-squars GOF test to test null hypothesis that the age distribution of drivers stopped in 2003 for traffic violations is the same as the age distr. in 2002. You compute chi-square= 14.7. At the 5% significance level, what is an appropriate conclusion? A p-...

You can set up an equation: 30%= .3, so you'll have .3x= 120 (where x is the number whose 30% is 120) x= 120/.3 x= 400 You can check by multiply .3 x 400= 120 So 30% of 400 is 120
