Question

A statistical program is recommended The following observations are on stopping distance (ft) of a particular truck at 20 mph under specified experimental conditions 32.1 30.8 31.7 30.4 31.0 31.9 The report states that under these conditions, the maximum alowable stopping distance is 30. A normal probability plot validates the assumption that stopping distance is normally distributecd. (a) Does the data suggest that true average stopping distance exceeds this maximum value? Test the appropriate hypotheses using α = 0.01 State the appropriate hypotheses. На: μ > 30 H0: μ # 30 Ha: μ-30 О но: μ-30 О но: #30 Ha: μ < 30 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) P-value - What can you conclude? O Reject the null hypothesis. There is not sufficient evidence to conclude that the true average stopping distance does exceed 30 ft. Do not reject the null hypothesis. There is sufficient evidence to conclude that the true average stopping distance does exceed 30 ft. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the true average stopping distance does exceed 30 ft O Reject the null hypothesis. There is sufficient evidence to conclude that the true average stopping distance does exceed 30 ft.

Please help me get the right values, I cannot figure it out. Please show your work.

Answer 1

Note:As per HOMEWORKLIB RULES 2 bits enough.Due to little confussion about c,d bits i couldn't solved.If you want to answer for answer for c,d bits please post it sepaartely.

Thank you.
