It is known that roughly 2/3 of all human beings have a dominant right foot or eye. Is there also right-sided dominance in kissing behavior? An article reported that in a random sample of 112 kissing couples, both people in 69 of the couples tended to lean more to the right than to the left. (Use α = 0.05.)USE SALT(a) If 2/3 of all kissing couples exhibit this right-leaning behavior, what is the probability that the number in a sample of 112 who do so differs from the expected value by at least as much as what was actually observed? (Round your answer to four decimal places.)(b) Does the result of the experiment suggest that the 2/3 figure is implausible for kissing behavior?State the appropriate null and alternative hypotheses.Ho: P = 2/3H₂: P ≤ 2/3Ho: P = 2/3H₂: P > 2/3O Ho: P = 2/3H₂: P < 2/3ⒸH₁: P = 2/3H₂:P # 2/3Calculate the test statistic and determine the P-value.

1 A decade-old study found that the proportion, p, of high school seniors who believed that "getting rich" was an important personal goal was 70%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 220 high school seniors in his random sample, 136 believe that "getting rich" is an important goal. Can he conclude, at the 0.05 level of significance, that the proportion has indeed changed? Perform a two-tailed test. Then complete the parts below.

An employee survey conducted by a company two years ago found that 53% of its employees were concerned about future health care benefits: A random sample of 80 of these employees were asked if they were now concemed about future health care benefits. Answer the following, assuming that there has been no change in the level of concern about health care benefits compared to the survey bwo years ago a What is the standard enor of the sample proportion who are concerned? b. What is the probability that the sample proportion is less than 0.507 cWhat is the upper limit of the sample proportion such that only 4% of the time the sample proportion would exceed this value?

Upon enrolling in State University, freshmen are required to take an English placement exam. Over the past several years, 20% of the new students have failed the test and have been placed in remedial classes. In a sample of n = 100 students from this year's class, only 12 failed the test. Do these data indicate a significant change from previous years? Assuming a two-tailed test, what is the null hypothesis?A. p = .20 B. p = 12/100 = .12 C. X = 12/100 = .12 D. X = 12
1. A university has 25,000 students, of whom 17,000 are undergraduates. The housing office takes a simple random sample of 500 students; 357 out of the 500 are undergraduates. Fill in the blanks.

For percentages, enter a number between 0 and 1) (a) For the number of undergraduates in the sample, the observed value is _________ but the expected value is ______________ (b) For the percentage of undergraduates in the sample, the observed value is ____________ but the expected value is ____________
About 40% of all US adults will try to inflate an insurance claim to cover the deductible. Suppose that you work at an insurance company and just received 128 insurance claims. You are interested in the number of inflated claims. Is it fair to say this represents a binomial setting? Explain. Would it be reasonable to use the normal approximation? Explain. What is the probability that more than 80 of the claims are inflated?
