Answer: There are 90 calories in a 6-ounce bottle.
Step-by-step explanation:
We assume that the quantity of juice in the bottle is directly proportional to the number of calories it contains.
Given: 10 ounces of juice has 150 calories.
i.e. 1 ounce of juice has calories.
i.e. 1 ounce of juice has 15 calories.
Now, In 6 ounce of juice, the number if calories = 15 x 6 = 90 calories
Hence, there are 90 calories in a 6-ounce bottle.
Answer:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
Step-by-step explanation:
1. Null and alternative hypothesis
2. Significance level
Freedom degrees is given by:
For a sgnificance level of 0,01 and 22 freedom degrees, t-student distribution value is:
3. Test statistic
In this case, we have an one left tailed analysis, it means that null hypothesis is rejected if
Conclusion:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
