In 1945, an organization asked 1446 randomly sampled American chizens, Do you think we can develop a way to protect ourselves from atomic bombs h case others tried to use them against us with 744 responding yes Dilda majority of the citizens feel the country could develop a way to protect itself from atomic bombs in 19157 Use the 01 level of significance What are the null and shemalive hypotheses? He (Type Integers or decimals) Determine the test sati, 26 2o-Round to two decimal places as needed) Une technology to determine the value for the test stic The values Round to the decimal places as needed) What is the correct conclusion at the a 0.1 level of sigcance? Since the values than the level of significance tomos the ruil hypothesis. There suficient evidence to conclude that the majority of the feel the country could develop a way to protected

Answer 1

= 0.5145 0.5145-0.5 n=1446 ; x = 744 In this 1446 Null Hypothesis Ho: P = 0.5 Alternate Hypothesis Ha:P >0.5 Test-statistic CZo) = P-P PLI-P) 0.561-0.5) 1446 Test - Statistic (ZO) = 11:10 P-value = PCZ >1.10) = 0.1357 C 0:136 P-value > significance level coc) 0.136 >oilo Fail to reject the null Hypothes's (Ho). Since P-value is greater than the level of significance. Fail to reject the nul Hypothesis. There is not sufficient evidence to conclude that the majority of citizens
