An amb v a service claims that the proportion, p, of calls received that involve life-threatening emergencies is greater than 59%. Can we support this claim at the 0.05 level of significance, if 72 calls out of a random sample of 115 calls selected from the service's files involved life-threatening emergencies? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H. H O P Ho : 1 X S P (b) Determine the type of test statistic to use. (Choose one) V O=0 050 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) * 00 (d) Find the p-value. (Round to three or more decimal places.) X ? (e) Can we support the claim that the proportion of calls received that involve life-threatening emergencies is greater than 59%
