Ali and Karim intend to investigate the average weight of LIU female students. They claim that the average weight of LIU female students is 65 kg. After collecting the necessary data (Ali selected a larger random sample than that selected by Karim) and performing the needed tests,
the following debate arised between them
Ali: At the 2% significance level, we can conclude that the average weight of LIU female students is 65 kg.
Karim: But we may not conclude that the average weight of LIU female students is 65 kg at the 6% significance level. a. State the null and the alternate hypotheses.
b. State the decision rule using p value.
c. Give an expectation of p value such that the claim is not rejected at the 2% but it is
rejected at the 6%.

CUNY advertises that the average class size is 35 students or less, with a standard deviation of 8 students. QCC SGA is concerned that budget cuts have led to increased class sized and would like to test this claim. A random sample of 38 classes was selected, and the average class size was found to be 36.9 students. Using a level of significance of 0.05, can QCC SGA conclude that the average class is greater than 35 students? a. State...

Please answer both!! Suppose the national average dollar amount for an automobile insurance claim is $805.66. You work for an agency in Michigan and you are interested in whether or not the state average is less than the national average. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≥ 805.66, Alternative Hypothesis: μ < 805.66. You take a random sample of claims and calculate a p-value of 0.02 based on the data, what is the appropriate conclusion?...

A nutrition expert claims that the average American is overweight. To test his claim, a random sample of 22 Americans was selected, and the difference between each person's actual weight and idea weight was calculated. For this data, we have x¯=18.2x¯=18.2 and s=29.4s=29.4. Is there sufficient evidence to conclude that the expert's claim is true? Carry out a hypothesis test at a 4% significance level. A. The value of the standardized test statistic: Note: For the next part, your answer...

1) The body weight of a healthy 3-month-old colt should be about μ = 62 kg. (a) If you want to set up a statistical test to challenge the claim that μ = 62 kg, what would you use for the null hypothesis H0? μ > 62 kgμ < 62 kg    μ = 62 kgμ ≠ 62 kg (b) In Nevada, there are many herds of wild horses. Suppose you want to test the claim that the average weight of a...

A recent national survey found that high school students watched an average (mean) of 7.6 DVDs per month with a population standard deviation of 0.5 hours. The distribution of times follows the normal distribution. A random sample of 61 college students revealed that the mean number of DVDs watched last month was 7.0. At the 0.01 significance level, can we conclude that college students watch fewer DVDs a month than high school students? Use α = 0.01. a. State the...
