A marine biologist claims that the mean length of mature female pink seaperch is different in fall and winter. A sample of 6 mature female pink seaperch collected in fallhas a mean length of 112 millimeters and a standard deviation of 15 millimeters. A sample of 8 mature female pink seaperch collected in winter has a mean length of99 millimeters and a standard deviation of 14 millimeters. At a = 0.20, can you support the marine biologist's claim?

Can someone help me with this please? Freshmen and Seniors For this assignment, you will conduct a two-sample t-test to determine if college freshmen and seniors have a significantly different number of speeding tickets. Using the data provided below, conduct a two-sample t-test. Speeding Tickets for Freshmen and Seniors Freshmen 2 1 4 2 5 1 0 2 4 2 Seniors 1 2 1 1 0 2 1 0 1 2 Then, create a summary of 1-2 paragraphs in which you address the following: • Present the result of the two-sample t-test. • Explain whether or not the result is statistically significant. • Discuss what this implies for freshmen and seniors, and whether or not the results fit with your own expectations.

Ramos has a spinning wheel. The Spining wheel has 18 blue numbers 18 white numbers and 2 yellow numbers the table provided shows the frequency with which the ball landed on each color in 200 trials. color blue frequency 18 white frequency 18 yellow frequency 2 . At the 5% significance level do the data suggest that the wheel is out of balance?you will need to compute the expected counts to do your calculations remember that the expected counts can be computed with the formula E = np, where n is the number of trials and P is the probability of each color.
