What are the null and alternative hypotheses? upper h 0: p equals 0.089 versus upper h 1: p greater than 0.089 (type integers or decimals. do not round.) because np 0 left parenthesis 1 minus p 0 right parenthesisequals 5.7 less than 10, the normal model may not be used to approximate the p-value. (round to one decimal place as needed.) find the p-value. p-valueequals 0.003 (round to three decimal places as needed.) is there sufficient evidence to support the economist's belief? a. yes, reject the null hypothesis. there is sufficient evidence because the p-value is less than alpha. your answer is correct. b. no, reject the null hypothesis. there is not sufficient evidence because the p-value is less than alpha. c. yes, do not reject the null hypothesis. there is sufficient evidence because the p-value is greater than alpha. d. no, do not reject the null hypothesis. there is not sufficient evidence because the p-value is greater than alpha.
