The two sided hypothesis of the given situation is H0 : p = 0.50 and Ha : p ≠ 0.50
in statistics, hypothesis is defined as a statement that explains the predictions and reasoning of your research.
Here we have given that cerebral tumors and cell phone use. in a case-controlled study on cerebral tumors and cell phone use, tumors occurred more frequently on the same side of the head where cellular telephones had been used in 26 of 41 cases.
And we need to find the test to the hypothesis that there is an equal distribution of contralateral and ipsilateral tumors in the population. use a two-sided alternative.
Here we have to find Hypothesis, for that we have to so the steps are shown below:
Let us considered the hypotheses for the study as shown below:
H0 : p =0.50
Versus,
Ha : p ≠ 0.50
Therefore, this is two tailed hypothesis test.
