t is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 123 feet. A transportation researcher wants to determine if the statement made in the advertisement is false. She randomly test drives 33 small cars at 65 miles per hour and records the braking distance. The sample average braking distance is computed as 116 feet. Assume that the population standard deviation is 21 feet.(You may find it useful to reference the appropriate table:ztableorttable) a.State the null and the alternative hypotheses for the test. multiple choice 1

a)H₀:= 123;H_A: 123

b)H₀: 123;H_A:< 123

c)H₀: 123;H_A:> 123

b.Calculate the value of the test statistic and thep-value.(Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.) Test Statistic = Find thep-value.

a)p-value 0.10

b)p-value < 0.01

c)0.01 p-value < 0.025

d)0.025 p-value < 0.05

e)0.05 p-value < 0.10

c.Use= 0.05 to determine if the average breaking distance differs from 123 feet.

a)differs

b)does not differ
