A knewton.com Question The following data was calculated during a study on customer experience. Use the following information to find the test statistic and p-value at a 10% level of significance: • The claim is that the percent of companies that view customer experience as the most vital component of a growing business is different than 50%. Sample size = 50 companies • Sample proportion = 0.40 Use the table or the curve below to find the test statistic and p-value. For the curve select the appropriate test by dragging the blue point to a right-, left- or two-tailed diagram, then set the sliders. Use the purple slider to set the significance level. Use the black sliders to set the information from the study described above. z 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 |-1.5 0.067 0.0660.064 0.063 0.062 0.061 0.059 o.058 0.057 0.056 -1.40.081 0.0790.078 0.076 0.075 0.074 0.072 0.071 0.069 0.068 |-1.3 0.097 0.095 0.093 0.092 0.090 0.089 0.087 0.085 0.084 0.082 -1.2 0.115…
