The average house has 14 paintings on its walls. Is the mean larger for houses owned by teachers? The data show the results of a survey of 14 teachers who were asked how many paintings they have in their houses. Assume that the distribution of the population is normal. 15, 13, 16, 16, 17, 14, 14, 15, 13, 13, 15, 16, 15, 16 What can be concluded at the a = 0.01 level of significance? a.

Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest that the population mean number of paintings that are in teachers' houses is not significantly more than 14 at a = 0.01, so there is insufficient evidence to conclude that…
Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitative.A psychologist wants to measure the effect of music on memory. He randomly selects 80 students and measures their scores on a memory test conducted in silence. The next day he measures their scores on a similar test conducted while classical music is playing. The mean score without music is compared to the mean score with music. Group of answer choices a.quantitative, dependent b.qualitative, independent c.qualitative, dependent d.quantitative, independent
In 1995, the median price of a PC was $1200. Suppose that a random sample of100 persons who bought their PCs during that year recorded the amount spent (byeach of them) on his/her PC. State the approximate sampling distribution of ˆp, theproportion of persons who spent more than $1200 on a PC. Find the probabilitythat more than 60% of this group spent more than $1200.
