My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and will not work. Materials/Methods For unit 7.3 the experiment needed 2 microfuge tubes one labeled

The first Hypothesis statement is; there is a difference in the coffee consumption rate of Americans based on gender. The second Hypothesis statement is; there is not a difference in the coffee consumption rate of Americans based on gender. The team will use the Confidence Interval to check if there is no significant difference

times of the standard deviation. This can be best expressed as in the equation of 2s = 2(12.28455) which equals 24.57 average hours per week. Then‚ we can analyze the accuracy of hypothesis model to see if the average number of hours per week (x) helps figure out y by using the least squares line. We test the null hypothesis that the slope (β1) is equal to 0 or less than 0. In other words‚ it means that average number of hours per week and work-life balance score do not have a linear relationship.

CHAPTER I The Problem and Its Background Introduction Education is instrumental in harnessing man’s potentials and capacities to make him a productive and effective member of society; hence the total development of the individual is the ultimate aim of education. Thus‚ schools were established in all feasible areas to quench man’s quest for further knowledge and optimum development. In effect‚ awareness to the significant benefits of education directed the school towards offering different courses
