Chapter 9: Q.7 (page 546)

A change is made that should improve student satisfaction with the parking situation at a local high school. Right now, 37% of students approve of the parking that鈥檚 provided. The null hypothesis H0:p>0.37is tested against the alternativeHa:p=0.37.

Short Answer

Expert verified

The population value is 0.37 as per null hypothesis and population value more than0.37 as per alternative hypothesis, the problem is incorrect according to the hypotheses.

Step by step solution

01

introduction

Given,

37% of students approve of the parking that鈥檚 provided and the hypotheses are tested against one another.

02

explanation

calculating the hypotheses,

population value =0.37as per null hypothesis

鈬�H0:p=0.37

population value more than0.37as per alternative hypothesis

鈬�Ha:p>0.37

The population value =0.37as per null hypothesis and population value more than0.37as per alternative hypothesis, the problem is incorrect according to the hypotheses.

The design of controls and instruments affects how easily people can use them. A student project investigated this effect by asking 25right-handed students to turn a knob (with their right hands) that moved an indicator. There were two identical instruments, one with a right-hand thread (the knob turns clockwise) and the other with a left-hand thread (the knob must be turned counterclockwise). Each of the 25students used both instruments in a random order. The following table gives the times in seconds each subject took to move the indicator a fixed distance:

(a) Explain why it was important to randomly assign the order in which each subject used the two knobs.

(b) The project designers hoped to show that right-handed people find right-hand threads easier to use. Carry out a significance test at the 5%significance level to investigate this claim

In planning a study of the birth weights of babies whose mothers did not see a doctor

before delivery, a researcher states the hypotheses as

H0:x炉=1000gramsHa:x炉<1000grams

Two-sided test The one-sample t statistic from a sample of n=25observations for the two-sided test of H0:渭=64;Ha:渭鈮�64has the value t=-1.12.

(a) Find the P-value for this test using (i) Table Band (ii) your calculator. What conclusion would you draw at the 5%significance level? At the 1%significance level?

(b) Redo part (a) using an alternative hypothesis of Ha:渭<64.

Healthy bones The recommended daily allowance (RDA) of calcium for women between the ages of 18and 24years is 1200milligrams (mg). Researchers who were involved in a large-scale study of women鈥檚 bone health suspected that their participants had significantly lower calcium intakes than the RDA. To test this suspicion, the researchers measured the daily calcium intake of a random sample of 36women from the study who fell in the desired age range. The Minitab output below displays descriptive statistics for these data, along with the results of a significance test.

(a) Determine whether there are any outliers. Show your work.

(b) Interpret the P-value in context.

(c) Do these data give convincing evidence to support the researchers鈥� suspicion? Carry out a test pg 571to help you answer this question.

Sampling shoppers A marketing consultant observes 50 consecutive shoppers at a supermarket, recording how much each shopper spends in the store. Explain why it would not be wise to use these data to carry out a significance test about the mean amount spent by all shoppers at this supermarket.
