Actuation Consulting and Enterprise Agility recently conducted a global survey of product teams with the goal of better understanding the dynamics of product team performance and uncovering the practices that make these teams successful. One question posed was "In which of the following ways does your organization support aligning members of a core product team?" Global respondents were offered five choices. (Data extracted from
www.actuationconsultingllc.com/blog/?p=285.) The most common response (31%) was "shared organizational goals and objectives linking the team." Suppose another study is conducted to check the validity of this result, with the goal of proving that the percentage is less than 31%.
a. State the null and research hypotheses.
b. A sample of 100 organizations is selected, and results indicate that 28 organizations respond that "shared organizational goals and objectives linking the team" is the supported driver of alignment. Use either the six-step critical value hypothesis-testing approach or the five-step p-value approach to determine at the 0.05 level of significance whether there is evidence that the percentage is less than 31%.
