More than 11% of people mind if others smoke near a building entrance. Express the null and alternative hypotheses in symbolic form for this claim.H0:H1:
Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A researcher claims that at least 82% of people had at least one health care visit in the past year. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim does not contain a statement of equality, it represents the hypothesis. (a) How should you interpret a decision that rejects the null hypothesis? There is evidence to V the claim that at least 82% of people had at least one health care visit in the past year. (b) How should you interpret a decision that fails to reject the null hypothesis? There is evidence to V the claim that at least 82% of people had at least one health care visit in the past year.

Claim: A minority of adults would erase all of their personal information online if they could. A software firm survey of 554 randomly selected adults showed that 38% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below. ... a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. (Type an integer or a decimal. Do not round.)
Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis?

9 12 18 The literature for a particular medical procedure says there is a 70% chance it is successful. A surgeon performing the procedure tells his patients that the proportion of procedures he performs that are successful is higher than that. In a random sample of 30 procedures performed by the surgeon, 24 were successful. Use the results of 75 simulations shown in the null distribution below to evaluate the surgeon's claim. 0.40 0.47 0.53 0.60 0.67 0.73 0.80 0.87 0.93 1
