QuestionSpeeding Tickets A motorist claims that the South Boro Police issue an average of 60 speeding tickets per day. The following data show the number of speeding tickets issued each day for a period of one month. Assume σ\sigma is 13.42 . Is there enough evidence to reject the motorist's claim at α=0.10\alpha=0.10 ? Use the PP-value method. Assume the variable is normally distributed. \begin{tabular}{llllllll} 57 & 60 & 83 & 26 & 72 & 58 & 87 & 48 \\ 59 & 60 & 56 & 64 & 68 & 42 & 57 & 58 \\ 63 & 49 & 73 & 75 & 42 & 63 & 57 & 60 \\ 72 & 45 & & & & & & \end{tabular} Send data to Excel
Part: 0/50 / 5
Part 1 of 5 (a) State the hypotheses and identify the claim. H0: (Choose one) H1: (Choose one) \begin{array}{l} H_{0}: \square \text { (Choose one) } \nabla \\ H_{1}: \square \text { (Choose one) } \nabla \end{array}
This hypothesis test is a (Choose one) \boldsymbol{\nabla} test. \square

Studdy Solution
There is *not* enough evidence to reject the motorist's claim that the South Boro Police issue an average of 60 speeding tickets per day at the α=0.10\alpha = 0.10 significance level.
The hypotheses are H0:μ=60H_0: \mu = 60 (the claim) and H1:μ60H_1: \mu \ne 60.
This was a two-tailed test.
