In a recent survey of 90 randomly selected college students, 59 said that they believe in the existence of extraterrestrial life. a) Find p, the sample proportion that believes that there is extraterrestrial life. (Round your answers to three decimal places). p = b) A recent report suggests the proportion of general US population who believe in extraterrestrial life is 0.47. Choose the appropriate null and alternative hypothesis that tests whether the prop of college students who believe in extraterrestrial life in greater than the general population? O Ho: P = 0.47 H₂: P = 0.47 O Ho: P= 0.47 H₂: p > 0.47 O Ho: P = 0.47 H₂: p > 0.47 O Ho: μ= 0.47 H₂:#0.47 O Ho: X = 0.47 H₂: x > 0.47 c) Calculate the z test statistic and p-value. (Round the test statistic to two decimal places and the p-value four decimal places). z = p-value =
