Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Where:
Now, we have to find the left tailed z critical value at 0.01 significance level using the standard normal table. The z critical value at 0.01 significance level is:
Conclusion: Since the test statistic does not fall in the critical region, therefore, we fail to reject the null hypothesis, and conclude that there is not sufficient evidence to say that the population proportion of women athletes who graduate from the university is now less than 67%.

213.71625
rounded to the nearest square foot: 214
Answer:
k<3.5 or k>3.5
Step-by-step explanation:
k²-7k+12.25>0
(k-3.5)²
k²-7k+12.25
k²-2k·3.5+(√12.25)²
(k-3.5)²
k-3.5<0 or k-3.5>0
k-3.5 or k-3.5
21/100 is in simplest form.
