When peforming a hypothesis test a sample is gathered to test the claim being made. When the sample evidence differs from the claimed​ value, how can you determine if that difference is just to do randomness or due to there being a statistically significant difference between the sample evidence and claimed​ value?

Answer #1

To determine if that the difference is just to do randomness we set level of significance which is set as to tolerable probability of randomness significancy. if the significancy is greater than level of significance than we say that there significant difference between the sample evidence and claimed value. here we use P_value to see the significance which is the probability of obtaining an effect atleast as extreme as the one in sample data by assuming the truth of the null hypothesis.

    6.   A claim is made that college students spend 75% of their time on either sleeping or socializing. You do not believe this claim, and you set out to conduct a hypothesis test with the following hypotheses: Ho:   p = 0.75 vs.   Ha:   p ≠ 0.75.   If you gather data from a sample and compute a test statistic equal to -0.6, what would the p-value be? 7.   Return to Question 6. The fact that the test statistic is negative tells...

    How do you know if a hypothesis test is testing the claim between 2 population proportions or 2 means? How is the test statistic for a claim about 2 population means, independent samples, standard deviations unknown, similar to the test statistic for 1 population mean, standard deviation unknown? If the difference between the 2 population means is not significant, which means the test statistic falls within the "usual" area of the distribution, what is the decision about the null hypothesis?...
