3.6 Triathlon times, Part ll: The distribution for triathlon time varies depending on the population you are describing. The distribution for men ages 30 - 34 is N(µ=4304, o=581). The distribution for women ages 25 - 29 is N(u=5225, o=848). Note, these distributions list the triathlon times in seconds. Use this information to compute each of the following. Report your answer to 2 decimal places. a) The cutoff time for the fastest 5% of athletes in the men's group, i.e. those who took the shortest 5% of time to finish. b) The cutoff time for the slowest 10% of athletes in the women's group.

The data in the accompanying table are from a paper. Suppose that each person in a random sample of 49 male students and in a random sample of 88 female students at a particular college was classified according to gender and whether they usually or rarely eat three meals a day. Find the test statistic and P-value. (Use SALT. Round your test statistic to three decimal places and your P-value to four decimal places.)

3.6 Triathlon times, Part II: The distribution for triathlon time varies depending on the population you are describing. The distribution for men ages 30 - 34 is N(µ=4337, o-593). The distribution for women ages 25 - 29 is N(H=5287, o=834). Note, these distributions list the triathlon times in seconds. Use this information to compute each of the following. Round all your answers to 2 decimal places. a) The cutoff time for the fastest 5.5% of athletes in the men's group, i.e. those who took the shortest 5.5% of time to finish. b) The cutoff time for the slowest 10% of athletes in the women's group.
As a researcher, you are interested if there is a significant difference in immunizations in those in low socioeconomic status and those in high socioeconomic status. To evaluate this you use the data below to calculate a Chi-Square (X2).

Copy the data to Desmos to draw a scatterplot of the data. Make sure to adjust the years so they represent years after 1980. a) Is it better to model the data with a linear or with an exponential model? [Select an answer b) Use regression in Desmos to find an appropriate model for f. Make sure to check Log mode in the parameter window in Desmos if you are fitting an exponential model. f(t) Round the coefficients to 4 decimal places. Hint: Use the variablet from the drop down menu when entering the equation. Do not just type in t. c) Predict the number of polio cases in 2013. d) Find the approximate half-life of the number of polio cases. Round the answer to one decimal place. years
