From birth, we struggle to be understood. We flail our arms, cry, scream, smile, frown, and make sounds and gestures to attract attention or to communicate our wants or needs. By adulthood, each of us has developed a unique way of communicating through gestures, words, expressions, and body language. Different cultures have different ways of expressing feelings and using body language. Members of some cultures gesture broadly; others maintain a closed body posture. Some are offended by direct eye contact, and others welcome a steady gaze. Although people differ in communication, this does not mean one sex, gender, culture, or group communicates better. We must be willing to accept differences and work to keep lines of communication open and fluid.

Consider the following hypotheses: ??: ? = 9,100 ??: ? ? 9,100 The population is normally distributed with a population standard deviation of 700. Compute the value of the test statistic and the resulting $p$-value for each of the following sample results. For each sample, determine if you can \"reject/do not reject\" the null hypothesis at the 10% significance level. Note: Negative values should be indicated by a minus sign. Round test statistic to 2 decimal places and $p$-value to 4 decimal places. a. $\bar{x}$ = 9,190, $n$ = 105 b. $\bar{x}$ = 9,190, $n$ = 255 c. $\bar{x}$ = 8,830, $n$ = 37 d. $\bar{x}$ = 8,860; $n$ = 37 Test statistic $p$-value
