1.) Using step 1 of the 5 to hypothesis, if I have no prior research to test a hypothesis refuting the use of electric fans accelerating body heat how can i find the appropriate null and alternative hypotheses ?
hypothesizing that the true population proportion of heart and core temperature increases amidst higher ambient temperature and humidity levels is less than 32% and setting the level of significance at 10% for the formal hypothesis test. You randomly sample 42 participants based on your research funding and for 45 minutes, the study participants sit in a chamber maintained at a temperature of 108 degrees Fahrenheit (i.e., 42 degrees Celsius) and a relative humidity of 70%. At the end of the 45 minutes, you record for all participants if his/her heart and core temperature increased as compared to the start of the time period.
Subjects (42) Heart and core temp increased in (8) of the subjects out of the 42
Please provided step by step to problem
2.) With using Step 2 of the 5-Steps to Hypothesis Testing, You decide to research further this seemingly contradictory guidance, hypothesizing that the true population proportion of heart and core temperature increases amidst higher ambient temperature and humidity levels is less than 35.5% and setting the level of significance at 10% for the formal hypothesis test. You randomly sample 35 participants based on your research funding and for 45 minutes, the study participants sit in a chamber maintained at a temperature of 108 degrees Fahrenheit (i.e., 42 degrees Celsius) and a relative humidity of 70%. At the end of the 45 minutes, you record for all participants if his/her heart and core temperature increased as compared to the start of the time period.
Subjects (35) Heart and core temp increased in (14) of the subjects out of the 35
