10. Obesity is a growing global health problem. According to Healthy Dining Finder, it is recommended to take no more than 750 calories for lunch. 400 adult customers were randomly selected during lunchtime at Wendy's in New York City, and the calorie consumption for each customer was observed. 400 adult customers were randomly selected during lunchtime at Wendy's in New York City, and the mean number of calories consumed was 817 and the standard deviation was 672. At the 5% significance level, a hypothesis test is performed to determine whether the sample provides a statistically significant evidence to conclude that the mean number of calories at Wendy's during lunchtime in New York City is more than the recommendation of 750 calories. A. Classify the hypothesis test as left-tailed, right-tailed, or two-tailed. Select one of the following: Left-tailed Right-tailed Two-tailed B. If the standardized test statistic is 1.99, what does this indicate? Read carefully and select one of the following: a) The observed sample mean of x 817 is 1.99 standard deviations more than the hypothesized population mean of u=750. b) The hypothesized population mean of u = 750 is 1.99 standard deviations less than the observed sample mean of x = 817. c) The observed sample mean of x = 817 is 1.99% more than the hypothesized population mean of u = 750. d) The hypothesized population mean of u = 750 is 1.99% less than observed sample mean of x= 817. %3D

Question
Transcribed Image Text:10. Obesity is a growing global health problem. According to Healthy Dining Finder, it is recommended to
take no more than 750 calories for lunch. 400 adult customers were randomly selected during lunchtime at
Wendy's in New York City, and the calorie consumption for each customer was observed. 400 adult
customers were randomly selected during lunchtime at Wendy's in New York City, and the mean number
of calories consumed was 817 and the standard deviation was 672. At the 5% significance level, a
hypothesis test is performed to determine whether the sample provides a statistically significant evidence to
conclude that the mean number of calories at Wendy's during lunchtime in New York City is more than the
recommendation of 750 calories.
A. Classify the hypothesis test as left-tailed, right-tailed, or two-tailed. Select one of the following:
Left-tailed
Right-tailed
Two-tailed
B. If the standardized test statistic is 1.99, what does this indicate? Read carefully and select one of
the following:
a) The observed sample mean of x = 817 is 1.99 standard deviations more than the hypothesized
population mean of u=750.
b) The hypothesized population mean of u = 750 is 1.99 standard deviations less than the observed sample
mean of x=817.
c) The observed sample mean of x = 817 is 1.99% more than the hypothesized population mean of u = 750.
d) The hypothesized population mean of u = 750 is 1.99% less than observed sample mean of x = 817.
