Based on a survey of a random sample of 900 adults in the United States, a journalist reports that A random sample of 100 movie goers was asked to state his or her gender and favorite soft drink available at the local movie theater. The results appear in the table below. Is there a relationship between gender and soft drink preference?

$\begin{array}{|cccc|}\hline & \text{Coke}& \text{Diet Coke}& \text{Sprite}\\ \text{Male}& 23& 11& 12\\ \text{Female}& 16& 28& 10\\ \hline\end{array}$

To analyze the results, which of the following tests is most appropriate?

A)Chi-square test of independence

B)Chi-square test of homogeneity

C)Two sample t-test

D)Matched pair t-test

E)Chi-square goodness of fit

The chi-square independence test is used to determine whether there is relation between two categorical variables or not.

In this study, the variables 'gender' and 'favorite soft drink' are both categorical. Also whether there is relation between these two variables or not has to be tested. This shows that, the appropriate test would be chi-square independence test.

Correct Answer: Option A) Chi-square test of independence.

For the 1s orbital of the Hydrogen atom, the radial wave function is given as: $R(r)=\frac{1}{\sqrt{\pi}}(\frac{1}{{a}_{O}}{)}^{\frac{3}{2}}{e}^{\frac{-r}{{a}_{O}}}$ (Where ${a}_{O}=0.529$ ∘A)

The ratio of radial probability density of finding an electron at $r={a}_{O}$ to the radial probability density of finding an electron at the nucleus is given as ($x.{e}^{-y}$).
