Find the p -value for the given information below. (ROUND TO 4 DECIMALS!) With \( H_{1}: p>0.29 \), the test statistic is \( z=1.97 \). Find the \( p \)-value for the given information below. (ROUND TO 4 DECIMALS!) The test statistic in a two-tailed test is \( z=-1.63 \). Find the \( p \)-value for the given information below. (ROUND TO 4 DECIMALS!) The test statistic in a left-tailed test is \( z=-1.72 \). Find the \( p \)-value for the given information below. (ROUND TO 4 DECIMAIS!) The test statistic in a right-tailed test is \( z=0.55 \). Find the \( p \)-value of the given information below. (ROUND TO 4 DECIMALS!) Claim: The mean time between uses of a TV remote control by males during commercials equal 5.00 sec . Sample Data: \( \mathrm{n}=81, \bar{x}=5.25, \mathrm{~s}=2.50 \mathrm{sec} \). The significance level is \( \alpha=0.01 \). U12. The graph shows the populations of the metropolitan areas A and B, over the years 2003-2008. In what years was the population of the metropolitan area B greater than that of the metropolitan area A? Choose the correct answer below. A. \( 2003-2006 \) B. \( 2006-2008 \) C. \( 2003-2005 \) D. \( 2005-2008 \) D Find the value of the test statistic \( z \) for the given information below. (ROUND TO 2 DECIMALS!) The claim is that the proportion of peas with yellow pods is equal to 0.25 , and the sample statistics include \( n=580 \) peas with \( 26.2 \% \) of them having yellow pods. Find the value of the test statistic \( z \) for the given information below. (ROUND TO 2 DECIMALS!) The claim is that the proportion of adults who shop using the Internet is less than 0.5 , and the sample include \( \mathrm{n}=1025 \) subjects with \( 29 \% \) saying that they use the Internet for shopping. Find the critical \( z \) value(s). Assume that the normal distribution applies. \( \alpha=0.02, H_{1}: p<0.19 \) 02.575 \( 0-1.96 \) 01.28 \( 0-2.05 \) Question 8 Find the critical \( z \) value(s). Assume that the normal distribution applies. \( \alpha=0.10, H_{1}: p>0.18 \) \( 0-1.96 \)
