**Question:**What is the P(t < -0.3) with a sample size of 13?**Explanation:**This query is asking about the probability $ P(t < -0.3) $ in the context of a t-distribution. The degrees of freedom (df) can be calculated as the sample size minus one, which in this case is $ 13 - 1 = 12 $ df. To find this probability, you would typically use a t-distribution table or statistical software, looking up the value for a t-score of $-0.3$ with 12 degrees of freedom.

Never Married People The percentage of males 18 years and older who have never married is 30.4 . For females the percentage is 23.6 . Looking at the records in a particular populous county, a random sample of 250 men showed that 73 had never married and 50 of 200 women had never married. At the 0.05 level of significance, is the proportion of men greater than the proportion of women? Use the P -value method and let p1 be the proportion of men.
