  1. In a simple random sample of size 94, there were 28 children under the age of 13. It is desired to test H0: pchild = 0.18 versus H1: pchild < 0.18.

i). Compute the sample proportion p.

ii). Compute the test statistic.

Do you reject H0 at the 0.05 level?

A nutritionist claims that children under the age of 10 years are consuming more than the U.S. Food and Drug Administration’s recommended daily allowance of sodium, which is 2400mg. To test the claim, she obtained a random sample of 75 children under the age of 10 and measured their daily consumption of sodium. The sample mean amount of sodium consumed was 2993 mg and the sample standard deviation was 1889 mg. Is there significant evidence to support the nutritionist’s claim...

To test H0: σ=70 versus H1: σ<70​, a random sample of size n equals 25 is obtained from a population that is known to be normally distributed. ​(a) If the sample standard deviation is determined to be s equals = 46.5​, compute the test statistic. ​(b) If the researcher decides to test this hypothesis at α=0.05 level of​ significance, use technology to determine the​ P-value. ​(c) Will the researcher reject the null​ hypothesis? What is the P-Value?

A simple random sample of 100 flights Airline 1 showed that 64 were on time. A simple random sample of 100 flights of Airline 2 showed that 80 were on time. Let p1 and p2 be the proportions of all flights that are were time for these two airlines. Is there evidence of a difference in the on-time rate for the two airlines? To determine this, test the hypotheses H0: p1 = p2 versus Ha: p1 ≠ p2 at a...

A medical researcher claims that 5% of children under 18 years of age have asthma. In a random sample of 300 children under 18 years of age, 24 children had asthma. Is this evidence that more than 5% of children under 18 years of age have asthma? The null and alternative Hypotheses for the Test are: HO : p = 0.05 HA : p > 0.05 The P-value for this test is 0.0086. What does the P-value mean in the...
