Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 678 randomly selected adults showed that 50.5% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim. The results v significantly v so there V sufficient evidence to support the claim that most adults would erase all of their personal information online if they could.
6- Hi Wonderful Bartleby Team (Thanks for all the help I do really aprecciate all you guys do) I need help with this exercise from stats. Thanks in advance
Please don't provide handwritten solution
Dentists A toothpaste company wants to declare in an ad that more than 80% of dentists recommend their toothpaste. The company performs a hypothesis test at the α = 0.05 significance level to test their claim. The company samples 800 dentists. Of these, 653 recommend their toothpaste. Let p represent the population proportion of dentists that recommend their toothpaste. b.Calculate the z or t statistic. (Do not use continuity correction. Round final answer to 4 decimal places) Statistic: c. Find the p-value. (Do not use continuity correction. Round final answer to 4 decimal places) p-value:
