A personality test has a subsection designed to assess the "honesty" of the test-tak subsection among the general population. You decide that you'll use the mean of a What is the minimum sample size needed in order for you to be \( 95 \% \) confident tha population standard deviation of scores on this subsection. Carry your intermediate computations to at least three decimal places. Write your minimum whole number that satisfies the requirements). (If necessary, consult a list of formulas.)

3. Box and Whisker Plot: Draw a box and whisker plot for the data provided and identify any outliers. \( 12,17,13,14,12,16,18,29,15,14,12,17,13,14,12,16,18,29,15,14,12,17,13 \), \( 14,12,16,18,29,15,14 \)

Find the median of these numbers.

De una muestra aleatoria de 1.203 estudiantes de contaduría de cierto año, el \( 20,2 \% \) afirı que la oferta laboral era muy mal pagada. De una muestra aleatoria de 1.203 estudian de empresariales en otro año posterior, el \( 13,2 \% \) compartían dicha opinión. Calcule un tervalo de confianza del \( 99 \% \) para la diferencia entre las proporciones poblacionales.

g) Of the " \( r \) " values below which would be reasonable for the scatterplot above? Explai your reasoning. \( r=-.94 \quad r=-.32 \quad r=.32 \quad r=.94 \)

20. Some researchers claim that herbal supplements such as ginseng or ginkgo biloba enhance human memory. To test this claim, a researcher selects a sample of \( n=25 \) college students. Each student is given a ginkgo biloba supplement daily for 6 weeks and then all of the participants are given a standardized memory test. Scores on the normalized test are \( \mu=70 \) and standard deviation of 15 . The sample of 25 students had a mean score of \( M=75 \). (8 points) a. Do the data indicate a significant effect of the herb on memory? Use a two-tailed test with \( \alpha=0.05 \). (Show all steps.)
