Assuming Your Hypothesis Is Supported Which of the Following Graphs

If a female cricket. There is an initial research hypothesis of which the truth is unknown.

Types Of Errors In Hypothesis Testing Statistics By Jim

Predicting the outcome of the experiment if your hypothesis is supported First review your hypothesis.

. Ill graph the same datasets in the histograms above but use normal probability plots instead. The P value of 003112 is significant at the alpha level of 005 but not 001. Based on the following data how would you answer these results.

Appropriate titles Appropriate labels for each axis Appropriate scales for each axis Correct units for the data Complete a rough sketch of each graph. θ θ 0 willlooklike oneofthefollowingthreeassertions. All you need to do is visually assess whether the data points follow the straight line.

Of interest is whether the. There are 5 main steps in hypothesis testing. The P value results are consistent with our graphical representation.

The p-value is the probability of getting your sample or a sample even further from H 0 if H 0 is true. Richest in oxygen supplies b. Because you found these two species coexisting in the same region where you collected them you form the following hypothesis and prediction.

It is believed that 70 of males pass their drivers test in the first attempt while 65 of females pass the test in the first attempt. θ θ 0 inwhichcasethenullhypothesisis θ θ 0 Theequalitysignis always. 2001-47 The hypothesis best supported by this graph is that these beetles are most active when the area is a.

State your research hypothesis as a null hypothesis and alternate hypothesis H o and H a or H 1. Your hypothesis states that female crickets respond to both the chirp rate of the males song and the local temperature when identifying potential mates. Perform an appropriate statistical test.

The test statistic is z ppo σp where but as youll see your calculator computes everything for you. 2005-37 This graph suggests that from 1840 to 1920 the carrying capacity for sheep in Tasmania was approximately. A test statistic is a standardized measure of the discrepancy between your null hypothesis H 0 and your sample.

When you perform a hypothesis test in Minitab you can choose to display an individual value plot a boxplot and a histogram with your results. Wettest from dew d. The typical line of reasoning in a hypothesis test is as follows.

Predicting the outcome of the experiment if your hypothesis is supported First review your hypothesis. Present the findings in your results. This is important as mis-stating the hypotheses will muddy the rest of.

The graph with a spike near 10 at 25 C. The first step is to state the relevant null and alternative hypotheses. Can you strongly support or refute your hypothesis based on this graph or is additional analysis needed explain.

Assuming your hypothesis is supported which of the following graphs predicts the response of the female cricket to the males song as the temperature of the females enclosure varies. Explain in one or two sentences what trend the reader should observe in. θ θ 0 inwhichcasethenullhypothesisis θ θ 0 3.

Matched or paired samples. θ θ 0 2. Using P values and Significance Levels Together.

Free from predators. Collect data in a way designed to test the hypothesis. Female crickets respond to both the chirp rate of the males song and the local temperature when identifying potential mates.

The graph that you produced in Part B is reproduced here. In the graph above the two shaded areas are equidistant from the null hypothesis value and each area has a. Assuming your hypothesis is supported which of the following graphs predicts the response of the female cricket to the males song as the temperature of the females enclosure varies.

A sample hardly ever matches your. For this type of graph the best approach is the. The next graph displays the results with the probability distribution of the number of heads under the assumption that the null hypothesis is true shown in red and the probability distribution of the number of heads under the assumption that the null hypothesis is false and the probability of a head is 07 is displayed in blue.

It is the number of standard errors that the sample lies above or below H 0. You can think of a test statistic as a measure of unbelievability of disagreement between H 0 and your sample. Based on the data and your graph was your hypothesis supported or refuted.

Graphs should have the following. Decide whether to reject or fail to reject your null hypothesis. These and other graphs can help you summarize your results and more fully interpret the statistical results of a hypothesis test.

Based on the data and your graph was your hypothesis supported or refuted. The smaller the p-value the stronger the evidence against the null hypothesis. To graph a significance level of 005 we need to shade the 5 of the distribution that is furthest away from the null hypothesis.

A hypothesis is a proposed idea that may explain an observation or phenomena. Coolest with some sunlight c. Using graphs to understand the results of a hypothesis test.

It is verified by testing it. If your P value is less than or equal to your alpha level reject the null hypothesis. If the data supports the hypothesis then we.

If the points track the straight line your data follow the normal distribution. From this hypothesis you make the following prediction.
