A survey reported that 77% of registered voters in California approved of allowing two people of the same gender to marry and have regular marriage laws apply to them. Among 18 to 39-year-old registered voters in California, 92% approved of gay marriage. 34% of Californian registered voters are between the ages of 18 and 39. Out of the voters who approved of gay marriage, what is the percentage that are between the ages of 18- 39?

As a part of a class project, a teacher brings a jar of 200 jawbreakers of three different colors, orange, red and white. Students must estimate the number of white jawbreakers in the jar. Suppose that after the jar is shaken well, one student draws 30 jawbreakers from the jar, of which 9 are orange, 11 are red and 10 are white. Give the students sample statistic for the percent of white jawbreakers in the jar. Round to the nearest whole #.
You are an education researcher interested in studying if race or ethnicity affects the severity of punishment children receive. Through open records, you are able to collect from several high schools the length of suspensions given to kids for fighting along with the race/ethnicity of the child. The state of Texas divides school children into one of 7 race/ethnicity groups: African American, American Indian, Asian, Hispanic, Pacific Islander, White, or Multiracial. You want to compare the average length of suspension among these 7 groups. Which statistical test would be best to determine if there is a significant difference in the severity of punishment among the different groups? one-sample t-test related samples t-test independent samples t-test ANOVA
A study in 2001, asked 792 college-age kids if they are attending a college and whether at least one of their parents had a college degree. Out of 445 college students, 214 stated that their parents did not have a college degree, and out of 347 teens not enrolled in a college, 298 indicated that their parents did not have a college degree. We would like to determine if the proportion of parents with no college-degree for teens who are not enrolled in a college is the same as that for teens who are enrolled in a college. 20.State the null and alternative hypothesis for this investigation in complete sentences and as mathematical equations. 21.

Lilo wants to know if equal proportions of students in her class know how to surf well, know how to surf a little or do not know how to surf. She randomly samples 60 students in her class and asks them if they know how to surf. Twenty students indicate that they do not know how to surf 'don't know', while 30 students indicate they know how to surf well 'know well,' and 10 students indicate they know how to surf ‘a little’. State the hypothesis being tested by Lilo (H0 and HA)? Test Lilo's hypothesis at α of .05. Enter the test statistic, critical value, and decision as part of your answer. Test statistic = Critical value = Do you reject or retain the null hypothesis that the slope is not different from zero? (Enter "Reject" or "Retain"):
