Determine whether the results appear to have statistical​ significance, and also determine whether the results appear to have practical significance. In a study of a gender selection method used to increase the likelihood of a baby being born a​ girl, 2086 users of the method gave birth to 1019 boys and 1067 girls. There is about a 15​% chance of getting that many girls if the method had no effect. Because there is a 15% chance of getting that many girls by chance, the method ______. ____ couples would likely use the procedure that raises the likelihood of a girl from the approximately 50% rate expected by chance to the ___% produced by this method.

When two births are randomly​ selected, the sample space for genders is​ bb, bg,​ gb, and gg. Assume that those four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births.

Does the mean of the sample proportions equal the proportion of girls in two​ births?

Does the result suggest that a sample proportion is an unbiased estimator of a population​ proportion?

For the entire​ population, assume the probability of having a boy is one half ​, the probability of having a girl is one half ​, and this is not affected by how many boys or girls have previously been born.

Here are the IQ test scores of 31 seventh-grade girls in a Midwest school district: 114 100 104 89 102 91 114 114 103 105 108 130 120 132 111 128 118 119 86 72 111 103 74 112 107 103 98 96 112 112 93 These 31 girls are an SRS of all seventh-grade girls in the school district. Suppose that the standard deviation of IQ scores in this population is known to be σ = 15. We expect the distribution of IQ scores to be close to Normal. Estimate the mean IQ score for all seventh-grade girls in the school district, using a 96% confidence interval. to

According to an article in Newsweek, the natural ratio of girls to boys is 100:105. In China, the birth ratio is 100:114 (46.7% girls). Suppose you don't believe the reported figures of the percent of girls born in China. You conduct a study. In this study, you count the number of girls and boys born in 150 randomly chosen recent births. There are 59 girls and 91 boys born of the 150. Based on your study, do you believe that the percent of girls born in China is 46.7? Conduct a hypothesis test at the 5% level. Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

Part (a) State the null hypothesis. H0: p ≥ 0.467 H0: p ≠ 0.467 H0: p ≤ 0.467 H0: p = 0.467

Part (b) State the alternative hypothesis. Ha: p > 0.467 Ha: p < 0.467 Ha: p = 0.467 Ha: p ≠ 0.467

Part (c) In words, state what your random variable P' represents. P' represents the percent of boys born in China. P' represents the number of girls born in China. P' represents the ratio of girls to boys in China. P' represents the percent of girls born in China. Part (d) State the distribution to use for the test. (Round your answers to four decimal places.) P' ~ ,

Part (e) What is the test statistic? (If using the z distribution round your answers to two decimal places, and if using the t distribution round your answers to three decimal places.) ---Select--- =

Part (f) What is the p-value? (Round your answer to four decimal places.) Explain what the p-value means for this problem. If H0 is false, then there is a chance equal to the p-value that the sample ratio is 59 out of 150 or less OR 81 out of 150 or more. If H0 is false, then there is a chance equal to the p-value that the sample ratio is not 59 out of 150 or less OR 81 out of 150 or more. If H0 is true, then there is a chance equal to the p-value that the sample ratio is 59 out of 150 or less OR 81 out of 150 or more. If H0 is true, then there is a chance equal to the p-value that the sample ratio is not 59 out of 150 or less OR 81 out of 150 or more

. Part (g) Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value. WebAssign Plot WebAssign Plot WebAssign Plot WebAssign Plot

Part (h) Indicate the correct decision ("reject" or "do not reject" the null hypothesis), the reason for it, and write an appropriate conclusion.

(i) Alpha (Enter an exact number as an integer, fraction, or decimal.) α =

(ii) Decision: reject the null hypothesis do not reject the null hypothesis

(iii) Reason for decision: Since α > p-value, we reject the null hypothesis. Since α < p-value, we reject the null hypothesis. Since α > p-value, we do not reject the null hypothesis. Since α < p-value, we do not reject the null hypothesis.

(iv) Conclusion: There is sufficient evidence to conclude that the percent of girls born in China is not equal to 46.7%. There is not sufficient evidence to conclude that the percent of girls born in China is not equal to 46.7%

. Part (i) Construct a 95% confidence interval for the true proportion. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to four decimal places.) WebAssign Plot
