Please I want to the learn how to solve them. So can you please show work?

8) Find the area of the indicated region under the standard normal curve. -1.13 [J 2.03 A) 01504 B) 00212 C) 0.1292 D) 0.8489 9) Find the Pvalue for the hypothesis test with the standardized test statistic 2. Decide whether to reject Hg for the level of significance a. Left-tailed test z = -1.83 a = 0.05 A) 0.0336; reject H0 B) 0.0672; fail to reject H0 C} 0.9664; fail to reject H0 D) 0.0672; reject H0 10) The Pvalue for a hypothesis test is P = 0007. Do you reject or fail to reject H0 when the level of signicance is or. = 0.01? A) reject H0 B) fail to reject 1-10 C) not sufficient information to decide 11) A pollster wishes to estimate the proportion of United States voters who favor capital punishment. How large a sample is needed in order to be 99% condent that the sample proportion will not differ from the true proportion by more than 4%? A) 849 B) 1037 C) 2073 D) 17 12) Ten pairs of points yielded a correlation coefficient r of 0.790. If a = 0.05, which of the following statements is correct if H0: ,0 = 0? (Do not calculate a t-value.) A) Because 0.790 is greater than 0.632, the null hypothesis is not rejected. B) Because 0.790 is greater than 0.632, the null hypothesis is rejected. C) There is no correlation between the variables. D) Because 0.790 is greater than 0.602, the null hypothesis is not rejected. Provide an appropriate response. Use the Standard Normal Table to find the probability. 13) IQ test scores are normally distributed with a mean of 105 and a standard deviation of 13. An individual's IQ score is found to be 126. Find the z-score corresponding to this value. A) -0.62 B) 0.62 C) 1.62 D) -l.62 14) Assume that the salaries of elementary school teachers in the United States are normally distributed with a mean of $32,000 and a stande deviation of $3000. If a teacher is selected at random, find the probability that he or she makes more than $36,000. A) 0.4040 B) 0.1056 C) 0.0918 D) 0.9082
