A cran apple juice blend is mixed in a ratio of cranberry to apple of 1 to 2.
Part A) Consider following table:
Part B) Since
you can state that these quantities are proportional with the ratio 1:2.
Answer:
2 pounds
Step-by-step explanation:
1 pound = 16 ounces
x pound = 32 ounces
Answer:
No. we cannot believe it as per hypothesis test done.
Step-by-step explanation:
Given that five hundred draws are made at random with replacement from a box of numbered tickets; 276 are positive.
To test the claim whether the proportion for positive numbers is 50% let us conduct a hypothesis test for proportions.
(Two tailed test at 5% significance level)
Sample proportion p =
Std error of p =
(assuming null hypothesis to be true)
Here P = 0.50
Test statistic = p difference/std error =
Z test is used for this proportion.
p value = 0.0198
Since p value <0.05 we reject null hypothesis
At 95% confidence level, there is statistical evidence to show that sample mean is not 50%
16cos(28). Type that in like last time.
