A researcher conducted a goodness-of-fit test by using categorical data. Her data consists of 9 categories. Her null hypothesis states that the data occur in each category with the same frequency. If she found the test statistic X² = 10.93: What is the degree of freedom of the x² statistic? What is the P-value of the goodness-of-fit test? (Round to 3 decimals) Given the significance level of 0.05, what can she conclude from the test? The data occur in each category with the same frequency. The data does NOT occur in each category with the same frequency.
You are interested in estimating the the mean weight of the local adult population of female white-tailed deer (doe). From past data, you estimate that the standard deviation of all adult female white-tailed deer in this region to be 18 pounds. What sample size would you need to in order to estimate the mean weight of all female white-tailed deer, with a 96% confidence level, to within 4 pounds of the actual weight? Use a critical value rounded to four decimal places.
Consider the discrete random variable X given in the table below. Calculate the mean, variance, and standard deviation of X. Round all answers to at least 4 decimal places. μl = 0²: = O = X P(X) 14 7 10 0.07 0.35 0.14 What is the expected value of X? 15 0.12 16 0.11 18 20 0.11 0.1
