- Is the hypothesis above a one-tail or a two-tail hypothesis?When the null hypothesis is found to be true, the alternative hypothesis must also be truePlease show step by step work: An original claim is made that 60% of American consumers are not comfortable with the use of drone delivery for merchandise. Hypothesis testing results in Rejection of the Null hypothesis. Using Figure 8-5 on page 366 of the text, clearly state the final conclusion reached from this hypothesis test.
- If the conclusion in a hypothesis test is to fail to reject H0H0, we can conclude that there is strong evidence that the null hypothesis is true.Can you give me four examples of null hypothesis? Write the corresponding alternative hypotheses such that the first two require a directional test of hypothesis and the other two a, a non directional test.PLEASE HELP WITH THE PROBLEM BELOW Let pm and pf be the respective proportions of male and female white-crowned sparrows that return to their hatching site. We observed that 124 out of 894 males and 70 out of 700 females returned. Does your result agree that there is no difference between the proportions of male and female white-crowned sparrows that return to their hatching site with α = 0.05? Formulate the hypotheses Finish the hypothesis testing and draw your conclusion (use p-value to test the hypotheses)
