A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the meantuition and fees for private institutions in California is greater than $35.000?

15. The following five questions are based on the paper "THE POWER OF TV: CABLE TELEVISION AND WOMEN'S STATUS IN INDIA" by Jesnsen and Oster that tries to causally explore how access to cable television in villages in India affects domestic violence, preference for a male child and the autonomy that women enjoy. The variable "Village has cable" is a dummy variable equal to 1 if the village has access to cable and 0 otherwise. The variable beating attitude is a continuous variable, where higher beating attitude indicates higher instance of domestic violence. The variable son preference is a dummy variable which is equal to 1 if the household expressed preference for a male child. The variable autonomy is also a continuous variable where a higher number indicates higher autonomy for women.

("Is the instruction effective, as indicated by higher y scores?" See Section 9-4.) 2. What is the key issue if these data are reasoning tests for a sample of men (x) and a separate sample of women (y)? ("Does the population of men have the same mean as the population of women?" See Section 9-3.) What is the key issue if each pair represents a math reasoning score x and a starting salary y in thousands of dollars? ("Is the starting salary associated with math reasoning?"
