Alignment Number Styles 228 In 2013, 43% of business owners gave a holiday gift to their employees. A 2014 survey of 53 business owners indicated that 31% plan to providea holiday gift to their employees. Is there reason to bel of business owners providing gifts has decreased at -0.01? (see a similar problem.) 61 71 l lieve the proportion exercise 40 on page 418 of your textbook for 23 For the hypothesis stated above... Question 1What is/are the critical value(s)? 25 z crit 26- Question 2What is the test statistic? 1.76 Question3What is the conclusicon? Daily Probiem

Explanation / Answer

Please note the sign of the Z critical in the question and the sign of inequality in the last part

p0 = .43
p = .31
n = 53

Q1) Z = -2.33 ( since it is one tailed)
Q2) Test statistic = (p-p0)/sqrt(p0*p0'/n) = (.31-.43)/(sqrt(.43*.57/53)) = -1.76
Q3) p-value is =.0392.

We fail to reject null hypothesis and conclude that there is no reason to believe that the propotion

of business owners providing gifts has decreased at alpha = .01
