Problem 60Multiple Choice

A study records the last digits of the ages in years of $90$ randomly selected patients. The frequencies for the digits $0$ through $9$ are shown below:

At the $0.05$ significance level, test whether the last digits are equally likely. What is the value of the chi-square statistic, and what is the conclusion?

$chi squared equals 1.554$

There is sufficient evidence to conclude that the last digits are not equally likely.

$chi squared equals 1.554$

There is insufficient evidence to conclude that the last digits are not equally likely.

$chi squared equals 3.325$

There is sufficient evidence to conclude that the last digits are not equally likely.

$chi squared equals 3.325$

There is insufficient evidence to conclude that the last digits are not equally likely.
