Question

100%

For a hypothesis test of the claim that the mean amount of sleep for adults is less than 9 hours, technology output shows that the hypothesis test has power of 0.4815 of supporting the claim that u<O hours of sleep when the actual
population mean is 7.0 hours of sleep. Interpret this value of the power, then identify the value of B and interpret that value.
Identify the value of B and interpret that value. Select the correct choice below and fill in the answer box to complete your choice.
(Round to four decimal places as needed.)
O A. The value B= indicates that there is a less than 50% chance of incorrectly recognizing that u<O hours when in reality µ=9 hours.
O B. The value B= indicates that there is a greater than 50% chance of incorrectly recognizing that u<O hours when in reality H=9 hours.
OC. The value ß =
indicates that there is a greater than 50% chance of failing to recognize that u<9 hours when in reality u=7.0 hours.
OD. The value ß =
indicates that there is a less than 50% chance of failing to recognize that u<o hours when in reality p=7.0 hours

Researchers recruited a sample of 40 female and 40 male heterosexual Caucasian undergraduate students from British universities for a study of the attractiveness of body types. Among adults, a body mass index (BMI, in kg/m2 ) value between 18.5 and 24.9is considered healthy, but attractiveness may not be entirely about health. Using a 3D computer avatar, participants built what they considered the ideal body of an adult of their own gender. The Minitab output for the mean ideal BMI of the women and of the men respectively is shown. From Barbie dolls to runway models, women in Western countries are exposed to unrealistically thin and arguably unhealthy body standards for their gender. Does the study provide evidence that young Caucasian women in British universities, on average, aim for an unhealthy ideal body type (corresponding to a BMI less than 18.5 )? test statistic,t = p-value =
