The article “How to Block Nuisance Calls” reported that in a survey of mobile phone users, 70% of those surveyed said that they received at least one nuisance all to their mobile phone in the last month. Suppose that this estimate was based on a representative sample of 600 mobile phone users. Using a significance level of 0.05, determine if there is evidence that more than 66% of all mobile phone users have received at least one nuisance call in the last month.
Fill in the hypotheses with the hypothesized value and inequality if appropriate. (without spaces between inequality and value)
Ho : p =
Ha: p
What is the value of the test statistic? Round to the appropriate decimals.
What is the P-value of the test statistic? Round to 4 decimals.
What is the conclusion of the hypothesis test? (Reject the null or Fail to reject the null)
Is there sufficient evidence to support the claim that more than 66% of mobile phone users recieved at least one nuisance call last month? (Yes or No)

A phone manufacturer wants to compete in the touch screen phone market. He understands that the lead product has a battery life of just 5 hours. The manufacturer claims that while the new touch screen phone is more expensive, its battery life is more than twice as long as that of the leading product.

Website design options include mobile-first (structured to optimize performance for users on phones and mobile devices) and responsive design (structured to optimize performance for users on desktop computers). Data were collected based on a random sample of the number of times users complained about website design on a given day. Five non-profit organizations with mobile-first design were studied, as well as six non-profit organizations with responsive design. The organizations are roughly comparable in terms of number of visitors and target...
