A researcher claims that the amounts of sugar in a certain brand of soft drink have a mean different from the 29 mg claimed by the manufacturer. Test this claim at the 5% level of significance. The mean sugar content in a random sample of 27 soft drinks is 32.8 mg with a standard deviation of 3 mg. What are the correct hypotheses?

Question
Transcribed Image Text:A researcher claims that the amounts of sugar in a certain brand of
soft drink have a mean different from the 29 mg claimed by the
manufacturer. Test this claim at the 5% level of significance. The
mean sugar content in a random sample of 27 soft drinks is 32.8
mg with a standard deviation of 3 mg.
What are the correct hypotheses? (Select the correct symbols and use decimal values
not percentages.)
Ho: Select an answer
?
mg
H1: Select an answer
mg
Original Claim = Select an answer +
Based on the hypotheses, find the following:
Critical value = ±
(Round to three decimal places.)
Test statistic =
(Round to three decimal places.)
p-value =
(Round to four decimal places.)
Shade the sampling distribution curve with the correct critical value(s) and shade the
critical regions. The arrows can only be dragged to t-scores that are accurate to 1
place after the decimal point (these values correspond to the tick marks on the
horizontal axis). Select from the drop down menu to shade to the left, to the right,
between or left and right of the t-score(s).
Shade: Left of a value
Click and drag the arrows to adjust the values.
