**Educational Content on Motor Competence and Handedness Study****Study Overview:**Lesley E. Tan conducted research examining the relationship between left-handedness versus right-handedness and motor competence in preschool children. The study involved 41 left-handed and 41 right-handed children, who were evaluated through various motor skill tests. The objective was to assess if there was any significant difference in motor competence based on handedness. The findings are summarized in the following table:**Table of Results:**| | Left-handed | Right-handed ||------------------------|-------------|--------------|| **Sample size** | 41 | 41 || **Sample mean** | 97.5 | 98.1 || **Sample standard deviation** | 17.5 | 19.2 |**Statistical Analysis:**Given the data, a two independent means Student's t-distribution hypothesis test is appropriate for determining the statistical significance of the difference in means between the two groups.**Instructions for Analysis:**To calculate the t-test statistic, use MiniTab or another statistical software tool. The possible results for the t-test statistic are: - -8.68- 7.48- -0.6- -0.15- 0.883**Conclusion:**The appropriate statistical test will help determine if there is a significant difference in motor competence between left-handed and right-handed preschool children. This kind of analysis aids in understanding the impact of handedness on motor skills development.

12) A state fish hatchery raises trout for stocking streams and lakes. The size of the fish at release time can be controlled to a fair degree by varying the rate of feeding. The target is a mean of 10 ounces; if the fish are too small, those who catch the fish aren’t happy. A random sample of 75 fish were weighed at time of release and it was determined that the mean was 9.66 ounces with a standard deviation of 0.86 ounces. Test to determine if the fish being released have a population mean less than 10 ounces at the 0.01 significance level.
estioh 20 For a 4-unit class like Statistics, students should spend average of 12 hours studying for the class. A survey was done on 27 students, and the distribution of total study hours per week is bell-shaped with a mean of 14 hours and a standard deviation of 2.6 hours. Use the Empirical Rule to answer the following questions. a) 68% of the students spend between hours and hours on Statistics each week. b) 95% of the students spend between hours and hours on Statistics each week. c) 99.7% of the students spend between hours and hours on Statistics each week.

A USA based cable broadband company wants to investigate whether it's east coasts customers have a higher average customer satisfaction score than compared to it's west coast customers. The customer survey asks for a score between 1 and 5, with 1 being poor and 5 being excellent. 174 east coast customers are surveyed, and the sample mean is 3.35 with a sample standard deviation of 0.51. For the west coast, 355 customers are surveyed, and the sample mean is 3.24 with a sample standard deviation of 0.52.
Fuel efficiency of Prius: Fueleconomy.gov, the official US government source for fuel economy information, allows users to share gas mileage information on their vehicles. The histogram below shows the distribution of gas mileage in miles per gallon (MPG) from 14 users who drive a 2012 Toyota Prius. The sample mean is 53.3 MPG and the standard deviation is 5.2 MPG. Note that these data are user estimates and since the source data cannot be verified, the accuracy of these estimates are not guaranteed. (a) The EPA claims that a 2012 Prius gets 50 MPG (city and highway mileage combined). Do these data provide strong evidence against this estimate for drivers who participate on fueleconomy.gov? The test statistic is: __________________(please round to two decimal places)The p-value:___________________________ for this hypothesis test is: (please round to four decimal places)(c) Please comment on the primary thing that is wrong about the following statement: There is sufficient evidence…

erik, a tourism expert, is researching the number of overnight stays at two large hotels. He collected data for 30 days and calculated that the average number of overnight stays in one hotel was 135 nights and the standard deviation was 22 nights, while in the other hotel the average was 22 nights. mean) 142 and the standard deviation 18 nights. erik used an appropriate hypothesis test to examine whether there was a difference in the distribution of the number of overnight stays in the two hotels (e. Used an appropriate hypothesis test to test if there is a difference in the variance in overnight stays at the two hotels). What is the value of the test statistic? 1.22 0.82 0.95 1.49 0.67
10. The Bank of New England is concerned about the amount of debt being accrued by customers using its credit cards. The Board of directors decided to install an expensive monitoring system if the mean for all the bank’s customers is greater than $2000. The bank randomly selected 100 credit card holders and determined the amounts they charged. For this sample group the mean is $2190 and standard deviation is $760. Use 0.02 level of significance to test the claim that the mean amount charged is greater than $2000. Based on the results of testing, will the monitoring system be implemented?
3. A psychologist expects gender differences in the mean number of times students check their Facebook per day. The psychologist asked 24 males and 24 females about their Facebook activity and found that the mean number of times for females was 12 whereas for males was 9. The study estimated the population standard deviation to be 5. Using the above information and α = .05, two-tailed, independent samples t-test, complete the following questions. a) What is the effect size of this study? b) What is the power of this study? c) Using the same effect size as 3a (and α = .05), how many total subjects would the researcher need to obtain the power of 0.96? d) Interpret your answer to the above question (3c). That is, what does power equal to 0.96 mean in the context of testing a hypothesis?
