Please complete the questions in the picture below. For the "H0" question, the drop down selections are "population mean (u) or M". The second drop down options are "less than, greater than, less than or equal to, greater than or equal to, and the mathematical symbol for can't equal". The selections for the third set of drop downs are 14.3 or 15.1. For the last sentence, the option is "one tailed test" or "two tailed test".

8. Formulating directional and nondirectional hypotheses The term "El Nino" refers to the warming of the central and eastern tropical Pacific waters that occurs every 3 to 7 years and typically lasts from 9 to 12 months. The 1997-1998 El Nino, the strongest ever recorded, affected climate patterns worldwide. Its effect, combined with an increasing trend in annual global temperatures, made 1998 the warmest year in the 20th century. Suppose you are a climatologist. You conduct a hypothesis test to determine whether the global mean temperature in the current year is greater than the global mean temperature in 1998. Assume that the global mean temperature in 1998 was 14.3 degrees Celsius (the population mean). You obtain a preliminary sample of temperatures from recording stations worldwide, which yields a sample mean of M = 15.1 degrees Celsius. Let u denote the global mean temperature in the current year. Formulate your null and alternative hypotheses by selecting the appropriate values in the blue dropdown menus that follow.
