A developmental psychologist would like to examine the difference in verbal skills for 6-year-old girlscompared with 6-year-old boys. A sample of n = 5 girls and n = 5 boys is obtained, and each child isgiven a standardized verbal abilities test. The data are as follows:Are these data sufficient to indicate a significant difference in verbal skillsfor 6-year-old girls and 6-year-old boys?

A special education teacher did research on whether or not there is a relationship between the number of students in his class and the number incidents of “acting out” behaviors exhibited by the autistic students in the classroom. He collects data for a year and aggregates them by month. He obtained the statistics below, r= -.863 R2=.74 b= -1.212294 a= 131.176598 10.) How does the presence of more students affect the incidents in the class? a) as students are added the incidences increase b) as students are added the incidences decrease c) the number of students does not affect acting out d) the number of students caused more incidents How much of the variability of acting out is explained by the number of students in the class?___________

16% of all Americans suffer from sleep apnea. A researcher suspects that a different percentage of those who live in the inner city have sleep apnea. Of the 337 people from the inner city surveyed, 47 of them suffered from sleep apnea. What can be concluded at the level of significance of α= 0.05? a. The test statistic= (please show your answer to 3 decimal places.) b. The p-value = (Please show your answer to 4 decimal places.)
here are the remaining subpart unaswered questions that was asked in the previous homework questions. Assume that a population of thousands of people whose responses were used to develop the anxiety test had scores that were normally distributed with u=30 and o=10. What proportion of people in this population would have anxiety scores within each of the following range of scores? Below 10 = Below 50 = Above 50 = Either below 10 or above 50 = What is SEm2? It is the sample estimate of the standard error of the mean. What does the value of SEm tell you about the typical magnitude of sampling error? It tells where a researcher has one sample of data of size N and the researcher can compute a sample mean, M, and a sample standard deviation, s, but the researcher does not know the values of the population parameter. As s increases, how does the size of SEm change (assuming that N stays the same)? As N increases, how does the size of SEm change (assuming that s stays the same)
Annie conducts a study to examine the differences in stress levels between pet owners and non-pet owners. She conducts a two-tailed test and tells that she rejected the null hypothesis. Therefore, which of these statements is true? Question 8 options: Pet owners have more stress than non-pet owners. Pet owners have less stress than non-pet owners. Pet owners' and non-pet owners' stress levels differ, but it is not known how they differ. Pet owners' and non-pet owners' stress levels do not differ.

In a survey taken in 2020, 20 out of 50 women and 17 out of 45 men said that they felt our country was headed in the wrong direction regarding universal health care. Do these data provide sufficient evidence at the 0.01 level of significance to conclude that the proportions of women and men that feel out country is headed in the wrong direction regarding healthcare are equal?
