A sample of size 50 is taken from a normal distribution, with a known population standard deviation of 26. The sample mean is 167.02. Use the 0.05 significance level to test the claim that the population mean is greater than 170. We always put equality in the null hypothesis, so our claim will be in the alternative hypothesis. H 0:μ=170. H ...

WebLevel of significance is used as a means to measure the statistical significance. When a researcher does research, he or she must first formulate a hypothesis, which is known as the null hypothesis.This hypothesis must be put to the … WebWe use p p -values to make conclusions in significance testing. More specifically, we compare the p p -value to a significance level \alpha α to make conclusions about our hypotheses. If the p p -value is lower than the significance level we chose, then we reject the null hypothesis H_0 H 0 in favor of the alternative hypothesis H_\text {a} H a.
WebFeb 6, 2024 · Hypothesis testing is guided by statistical analysis. Statistical significance is calculated using a p-value, which tells you the probability of your result being observed, given that a certain statement (the null hypothesis) is true. If this p-value is less than the significance level set (usually 0.05), the experimenter can assume that the null hypothesis … WebDec 31, 2024 · Using p < 0.05 is often inappropriate. When undergrad students of data science, economics, or statistics are introduced to statistical inference, they learn how to perform hypothesis testing using a default confidence interval of 0.95. The use of 0.95 — or the equivalent p < 0.05 — is widespread in both teaching, research, and when ...
