Suppose we want to test the hypothesis of \( H_0: \mu \geq 1 \) versus \( H_a: \mu < 1 \), and a random sample of \( n = 49 \) gives mean \( \bar{x} = -1 \) and standard deviation \( s = 6.4516 \). What is the \( p \)-value of the test?

(a) \( p \)-value = 0.005

(b) \( p \)-value = 0.010

(c) \( p \)-value = 0.015

(d) \( p \)-value = 0.020

(e) \( p \)-value = 0.025

The level of nitrogen oxides (NOX) in the exhaust of a particular car model varies with mean 0.9 grams per mile and standard deviation 0.2 grams per mile. (a) What sample size is needed so that the standard deviation of the sampling distribution is 0.01 grams per mile? Hint: You already have an equation that gives a relationship between the population standard deviation, the sampling distribution's standard deviation, and the sample size. Do a little algebra to solve that equation for the sample size. ANSWER: (b) If a smaller sample is considered, the standard deviation for ?¯ would be . (NOTE: Enter ''SMALLER'',''LARGER'' or ''THE SAME'' without the quotes.)

We wish to test the hypotheses HO: u 80 versus H1: H# 80 at a 14% level of significance. Here u denotes the average score X on a standardized test for students who have taken a preparation course for the exam. These hypotheses will be tested by obtaining a random sample of 600 student scores. If TS denotes (x-80) the test statistic where s is the sample standard deviation of the 600 V600 student scores, then the rejection rule may be stated as: Reject u = 80, if TS> 1.75 or TS 1.96 O Reject u 80, if TS > 1.75 or TS 1.48 or TS 1.48 or TS < -1.48
Blood platelet counts of women have a bell-shaped distribution with a mean of 255.1 and a standard deviation of 65.4 (all units are 1000 cells/µL). Using the empirical-rule, what is the approximate percentage of women with platelet counts (a) Within 2 standard deviation of the mean, or between 124.3 and 385.9 [1] (b) Between 189.7 and 320.5
produced by a steel industry company has an average length of 80 cm and a standard deviation of 7 cm. After 3 years, the company's technicians doubted the above hypothesis. A random sample of 100 steel plates is selected from the population above and the results of the average length measurement are 83 cm. Technicians still believe that the standard deviation is fixed. Is there any reason to doubt that the average length of steel plate produced by the factory has changed?
