ENTO 322-700 Discussion Article ID: 1c What is the hypothesis being tested by this research? [Reframe the primary question to be answered as a hypothesis if there is no direct hypothesis stated] The hypothesis being tested by this research was to see if a $20 device called a GAT could lure male mosquitos to a trap. If the mosquitos can be lured then researchers will be able to monitor them and sterilize them making it easier to monitor the population. What general methods/approaches are used in the

Elements of a Test of Hypothesis 1. Null Hypothesis (H0 ) - A statement about the values of population parameters which we accept until proven false. 2. Alternative or Research Hypothesis (Ha )- A statement that contradicts the null hypothesis. It represents researcher’s claim about the population parameters. This will be accepted only when data provides sufficient evidence to establish its truth. 3. Test Statistic - A sample statistic (often a formula) that is used to decide whether to reject H0

we’ve done the computation of the Z test statistic. For each of the following situations determine the p-value that goes along with Z. a. Z = 2.12‚ two-sided test b. Z = 4.55‚ two-sided test c. Z = -1.40‚ lower-tail test 2. Suppose Z = 1.92.Which has a smaller p-value‚ the upper-tail test or the two-sided test? From this‚ is it more likely to have a result that is significant at the 5% level using-a one-sided test or using a two-sided test? 3. Agricultural researchers at K-State sometimes study

Hypothesis 3: Mel Giedroyc will use tag questions‚ empty adjectives and politeness strategies in order to appear more welcoming on her radio show I hypothesised that on her radio show‚ Mel Giedroyc would use much more stereotypical ‘women language’ than her male host Bush as well as Nick Grimshaw. This is supported by Robin Lakoff’s gender deficient model which proposes that women speak in such a way that benefits men and makes them look good. She also developed the ‘politeness principle’ in which

The Life Cycle Hypothesis Formulated by Franco Modigliani of MIT. 1. The theory basically says that individuals plan their consumption and savings behaviour over the long term with a view of allocating incomes in the best possible way over their entire lifetimes. 2. This implies different marginal propensities to consume out of permanent income‚ transitory income (temporary) and wealth. 3. The basic idea is that individuals will spend the different incomes differently with a view

Research Questions: 1. How does temperature influence the population of fruit flies? 2. Do fruit flies reproduce faster in cool or warm temperatures? ie. Is the reproduction rate of fruit flies faster in warm temperatures or cooler temperatures? Hypothesis: Using two separate 750g boxes of peaches‚ one box placed in a warm environment (in front of a window allowing direct sunlight onto the peaches)‚ while the other is placed in a cool environment (beneath the kitchen sink)‚ over a period of two weeks

Research objectives are the goals of the research study. Research objectives specify the reason researchers are conducting research. For example‚ researchers may want to better understand the difference in pain scale results among subjects with a diagnosis of moderate traumatic brain injury. In this case the research objective would cause researchers to take steps to conduct scientific analysis to determine the variations in pain experienced between a group of individuals without a diagnosis of TBI
