Guide a hypothesis test by establishing Hypothesis, - Type of test, - Decision rule, and conclusion and if necessaryconfidence interval for the value of the parameter.1. A sample of 10 Latin American countries was obtained to find out what is invested in sports, that is, in promotinghigh performance, infrastructure, physical activity programs, promotion, salaries and scholarships. The information inmillions of dollars is as follows: 30.3, 842.4, 213, 169.3, 62.1, 52.5, 233, 65.3, 32.8, 50.2. Based on this information,could you ensure that the variance with respect to the average investment is greater than 60,516 million dollars? Usealpha=5%.
