According to a dental association, 68% of all dentists use nitrous oxide (laughing gas) in their practice. In a random sample of 500 dentists, let p represent the proportion who use laughing gas in practice. Complete parts a through d below. a. Find E(p). E (6) (Round to two decimal places as needed.) = b. Find on. p (Round to four decimal places as needed.) c. What does the Central Limit Theorem say about the shape of the sampling distribution of p? O A. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will become approximately normal. OB. The Central Limit Theorem says that the shape of the sampling distribution of p is completely determined by the population parameter p. С. The Central Limit Theorem does not say anything about the sampling distribution of p because it is not a population mean. O D. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will approach the population…

A researcher thinks that watching violent televisions increases aggressive behavior in children. To test this hypothesis, she randomly assigns 48 children into one of 3 groups (no violent TV, a little violent TV, or a lot of violent TV) and observes their playground behavior for three weeks and measures it for violence and intensity. For the variable “amount of TV” (as it appears in this problem), what is the scale of measurement? a. nominal b. ordinal c. interval d. ratio A researcher thinks that watching violent televisions increases aggressive behavior in children. To test this hypothesis, she randomly assigns 48 children into one of 3 groups (no violent TV, a little violent TV, or a lot of violent TV) and observes their playground behavior for three weeks and measures it for violence and intensity. If the researcher’s hypothesis is correct, which of the following conclusions could be drawn? a. Fail to reject the null, watching violent TV does not increase…
Autism Spectrum Disorder (ASD) is a group of complex brain development disorders that impacts how a person perceives and socializes with others, causing problems in social interaction and communication. The disorder also includes limited and repetitive patterns of behaviour. The age group (in months) at diagnosis of 60 people living with ASD are tabulated in the frequency distribution below: Age when ASD was diagnosed Class Midpoint Frequency (in months) M f (0 – 10] 12 (10 – 20] 15 20 (20 – 30] 25 13 (30 – 40] 35 9.
