The National Longitudinal Study of Adolescent Health interviewed several thousand teens (grades 7 to 12). One question asked was, "What do you think are the chances you will be married in the next 10 years?" Here is a two-way table of the responses by gender:| Opinion | Female | Male ||---------------------------------|--------|------|| Almost no chance | 137 | 86 || Some chance but probably not | 133 | 170 || A 50-50 chance | 438 | 525 || A good chance | 725 | 709 || Almost certain | 1191 | 739 |**Instructions:**Round your answers to three decimal places, if necessary.1. **How many total participants are seen in this table?** [Your Answer Here]2. **Of the respondents, how many identify as female?** [Your Answer Here]3. **The percent of females among the respondents was about [Your Answer Here]%.

Does money buy happiness? This is an age-old question. A random sample of 1993 subjects were asked to rate their happiness (Not too happy, Pretty happy, or Very happy) and also report their level of income (Above average, average, below average). The table of the observations is presented below. Income Not too happy Pretty happy Very happy Total Above Average 26 233 164 423 Average 117 473 293 883 Below Average 172 383 132 687 Total 315 1089 589 1993
. Historically (from about 2001 to 2005), about 58% of Americans believed that Earth’s temperature was rising (“global warming”). A March 2010 Gallup Poll sought to determine whether this proportion had changed. The poll interviewed 1014 adult Americans, and 527 said they believed that global warming was real. (Assume these 1014 adults represented a simple random sample.) (a) What percentage in the sample believed global warming was real in 2010? Is this more or less than the historical 58%? (b) Test the hypothesis that the proportion of Americans who believe global warming is real has changed. Use a significance level of 0.05. (c) Choose the correct interpretation: In 2010, the percentage of Americans who believe global warming is real is not significantly different from 58%. In 2010, the percentage of Americans who believe global warming is real has changed from the historical level of 58%.

Question: In a class of 50 students, the scores on a statistics exam are as follows: 10 students scored 80, 15 students scored 70, 20 students scored 60, and the rest scored 50. What is the mean score on the exam?
The following data represent the number of siblings (brothers and sisters) in the families of 20 students who were surveyed. O siblings = 2, 1 sibling = 3, 2 siblings =7, 3 siblings = 2, 4 siblings = 2. What is the probability of randomly selecting a student with 2 or more siblings? Input three-decimal fraction or percentage. Answer:
Are birthdays "evenly distributed" throughout the year, or are they more common during some parts of the year than others? Owners of a children's toy store chain in the Northwest asked just this question. Some data collected by the chain are summarized in the table below. The data were obtained from a random sample of 190 people. The birthdate of each person was recorded, and each of these dates was placed into one of four categories: winter (December 21-March 20), spring (March 21-June 20), summer (June 21-September 20), and fall (September 21-December 20). The numbers in the first row of the table are the frequencies observed in the sample for these season categories. The numbers in the second row are the expected frequencies under the assumption that birthdays are equally likely during each season of the year. The bottom row of numbers gives the following value for each of the season categories. Answer the following to summarize the test of the hypothesis that birthdays are equally…
Another question asked for a ranking of the condition of the road, based on the type of road. For the road types of interstate highway, U.S. highway, state (“M") highway, and local roads, residents were asked to evaluate the current condition, with choices of good, bad, or neutral. Researchers wish to evaluate if there is some relationship between the type of road and the road condition. This is a O Hypothesis test O Confidence interval For One proportion One mean O Paired mean O Difference in two means O Slope for a linear relationship O Chi-square goodness-of-fit O Chi-square test of independence
