in hypothesis testing if the null hypothesis is rejected -the alternative hypothesis is likely to be true - no conclusions can be drawn from the test -the data must have been accumulated incorrectly -the sample size has been to small

Using the information posted in the table, what is the null hypothesis and alternative hypothesis? Identify the test statistic and p-value from your source data. Would you reject or fail to reject your null hypothesis? Explain how you came to this conclusion (i.e. either use the test-statistic or p-value to support your claim). Would there be sufficient evidence (based upon your source data) to support the claim that those treated with magnets have a greater mean reduction in pain than...

What is a hypothesis? Provide an example of a "null hypothesis" and an "alternative hypothesis"

Please explain null versus alternative hypothesis (statistics hypothesis testing). Which is the pessimistic one?

Two key concepts in hypothesis testing are the null and the alternative hypothesis. Formulating the hypothesis test in the right manner, i.e. by correctly formulating null and alternative hypothesis is the first step towards solving the problems in the right manner. How do we represent these concepts tl (i.e. what abbreviation we use to denote null and alternative hypothesis)?

In hypothesis testing, we can reject a. the null hypothesis. b. the alternative hypothesis. c. both...

In hypothesis testing, we can reject a. the null hypothesis. b. the alternative hypothesis. c. both the null and the alternative hypotheses. d. neither the null and the alternative hypotheses.

Hypothesis testing conceptual questions: a. Define the null and alternative hypothesis b. What are the two errors that can occur in hypothesis testing? What mathematical symbols are used to denote these errors? c. Define the P-value. How are P-values used in hypothesis testing? d. How is the significance level of a hypothesis test determined? e. What assumptions must your data meet in order to perform a hypothesis test?

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses both the claim and the significance level alpha. Use the P-value method. A sample of 17 jellybeans with a mean weight of 0.8295 g was taken. Assume that σ is known to be 0.0565 g. Consider a hypothesis test that uses a 0.05 significance level to test the claim that the mean weight of all jellybeans is equal to 0.8550 g...

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Various temperature measurements are recorded at different times for a particular city. The mean of 20°C is obtained for 60 temperatures on 60 different days. Assuming that test the claim that the population mean is 22°C . Use a 0.05 significance level. Testing Hypothesis Z-Table

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. a) A poll of 1068 adult Americans reveals that 48% of the voters surveyed prefer the Democratic candidate for the presidency. At the 0.05 level of significance, test the claim that at least half of all voters prefer the Democrat. b) In a sample of 167 children selected randomly from one town, it is found that 37 of...
