Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 481 randomly selected adults showed that \( 64 \% \) of them would erase all of their personal information online if they could. Find the value of the test statistic. The value of the test statistic is (Round to two.decimal places as needed.) Claim: Fewer than \( 97 \% \) of adults have a cell phone. In a reputable poll of 1113 adults, \( 90 \% \) said that they have a cell phone. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as reeded.) Claim: The mean pulse rate (in beats per minute) of adult males is equal to \( 69 \mathrm{bpm} \). For a random sample of 148 adult males, the mean pulse rate is \( 67.6 \mathrm{bpm} \) and the standard deviation is \( 11.5 \mathrm{bpm} \). Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.) Claim: The standard deviation of pulse rates of adult males is less than \( 12 \mathrm{bpm} \). For a random sample of 154 adult males, the pulse rates have a standard deviation of \( 11.7 \mathrm{bpm} \). Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)
