A national internet service provider (ISP) claims that its broadband internet download speed is 100megabits per second (Mbps) on average. To the contrary, there have recently been widespread reports thatconsumers are experiencing much slower download speeds from this ISP. A organization ogranizationdecided to investigate the issue. They took a random sample of 16 internet speeds from around the nation.The observations are given below.10698931099187858699908887848610491Using a = 0.1, test the hypothesis that the average download speed is 100 Mbps, as advertised by the ISP.Assume that the distribution of all broadband internet download speed measurements from this ISP isapproximately normally distributed. Use the critical value method. Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. Ifmore than one critical value exists, enter the solutions using a comma-separated list.

An amusement park keeps track of the percentage of individuals with season passes according to age category. An independent tourist company would like to show that this distribution of age category for individuals buying season passes is different from what the amusement park claims. The tourist company randomly sampled 200 individuals entering the park with a season pass and recorded the number of individuals within each age category. Age Category Child (under 13 years old) Teen (13 to 19 years old) Adult (20 to 55 years old) Senior (56 years old and over) Number of Individuals 56 86 44 14 The tourist company will use the data to test the amusement park’s claim, which is reflected in the following null hypothesis. H0:pchild=0.23H0:pchild=0.23, pteen=0.45pteen=0.45, padult=0.20padult=0.20, and psenior=0.12psenior=0.12.

According to the NIMH website the average number of adult Americans diagnosed with a “serious mental illness” across all 50 states in 2019 was μ = 5.2 out of 100 residents (or 5.2%). Please test to see if the sample of states listed below (n=8) has a significantly higher level of mental illness than the population mean of 5.2. Sample data: Arkansas= 5.45%, Montana=5.34%, Vermont=5.32%, Oregon=5.19%, Utah=5.2%, Ohio=5.13, Kentucky=5.25% West Virginia=5.18%. Hint - drop the % signs and use 5.45, 5.32, etc as the X scores. If you want you can use JASP for help with the calculations. Use 3 decimal places for the M, s, SEM. The alpha level for the study was set to α=.05. a. State the hypotheses of the study. b. Find the critical t value for this studyc. Compute the one-sample t test. d. Compute the Cohen's d for the data (even if not significant) e. State the results - is the sample significantly higher? Do you reject the null hypothesis? Report the t test results in APA format…
