Question

Provide an appropriate response. Determine whether the normal sampling distribution can be used. The claim is p> 0.015 and the sample size is n-150 Use the normal distribution O Do not use the normal distribution QUEST 12.5 points Save Answer A telephone company claims that 20% of its customers have at least two telephone lines. The company selects a random sample of 500 customers and finds that 88 have two or more telephone lines. If a= 0.05, test the company's claim using critical values and rejection regions. Standardized test statistic 2-1.34; critical value zo = +1.96; fail to reject Ho; There is not sufficient evidence to reject the company's claim. Standardized test statistic -1.34; critical value zo = +2.576; fail to reject Ho; There is not sufficient evidence to reject the company's claim. Standardized test statistic<+1.96; critical value zo = -1.34; reject Ho: There is sufficient evidence to reject the company's claim. Standardized test statistic = 1.34; critical value zo = 1.96; fail to reject Ho; There is not sufficient evidence to reject the company's claim.
