Based on what we know about infants' use of statistical learning, what might explain individual differences in the number of words children understand by 1 year of age? (Remember, the median number of words known is 70, with the 10th percentile knowing 25 words and the 90th percentile knowing >200 words). Answers: Individual differences in reinforcement for listening to speech. Individual differences in number of words heard. Individual differences in categorical perception.

In Statsville there’s a city-wide speed limit of 30 mph.If you are caught speeding the fine is $100 plus $10 forevery mile per hour you were over the speed limit. Forexample, if you’re ticketed for going 45 mph, your fine is100 + 10145 - 302 = +250. Last month all the driverswho were fined for speeding averaged 42 mph with astandard deviation of 7 mph. What were the mean andstandard deviation of the fines?A) $120 and $70 B) $220 and $7C) $220 and $70 D) $220 and $170E) $420 and $70

A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6     Mean: 12.7 Mean: 13   Since the simulation shows ( many cases or free cases )?  where a mean  difference of ( solve for this answer )   or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely )  ?due to the random assignment of participants into groups, so the results of the study are (…
