For part d, my answer is incorrect. Can you help me determine the correct inputs and why?

Suppose the mean IQ score of people in a certain country is 101. Suppose the director of a college obtains a simple random sample of 42 students from that country and finds the mean IQ is 104.4 with a standard deviation of
13.7. Complete parts (a) through (d) below.
**- -- - - T --------
0.256 (Round to three decimal places as needed.)
Write a conclusion for the test. Choose the correct answer below.
O A. Do not reject Ho. There is not sufficient evidence to conclude that the mean IQ score of people in the country is greater than 103 at the a = 0.01 level of significance.
O B. Do not reject Ho. There is sufficient evidence to conclude that the mean IQ score of people in the country is greater than 103 at the a= 0.01 level of significance.
O C. Reject Ho. There is sufficient evidence to conclude that the mean IQ score of people in the country is greater than 103 at the a= 0.01 level of significance.
O D. Reject Ho. There is not sufficient evidence to conclude that the mean IQ score of people in the country is greater than 103 at the a= 0.01 level of significance.
(d) Based on the results of parts (a)-(c), write a few sentences that explain the difference between "accepting" the statement in the null hypothesis versus "not rejecting" the statement in the null hypothesis.
One should
ассept
rather than not reject the null hypothesis. If one does not reject the null hypothesis, this indicates that the population mean is a specific value, such as 101, 102, or 103, and so the same data have
been used to conclude that the
sample mean
is three different values, If one
ассepts
the null hypothesis, this indicates that the
sample mean
could be 101, 102, or 103 or even some other value; we are simply
not ruling them out as the value of the population mean.
Therefore,
accepting the null hypothesis can lead to contradictory conclusions, whereas not rejecting does not.

A marketing firm wishes to test the effectiveness of the audio/visual presentation of certain information as opposed to the purely audio presentation of the information. To this end 100 volunteers were given a 10 minute presentation in which the information was presented in an audio/visual format. A second group of 100 volunteers was presented the same information in a purely audio format. Each person in each of the two groups was asked the same 20 questions related to the information in the presentation. The audio/visual group had an average of 10.5 correct responses with a sample standard deviation of 4. The purely audio group had an average of 9.4 correct responses with a standard deviation of 3. The marketing firm believes this means that the audio/visual format leads to better retention of the information. We test the hypotheses H0: 1 -2=0 versus Ha: 1 -2>0 at a 2% level of significance.

In a traditional class with in-class tests, a question that is often asked after a class exam is, "What was the class average?" If that question is asked and the professor says that the class average was 80, what information do the students gain by knowing that? I want you to focus on both what the individual students knows about their own grade as well as what the students know about the class's grades on that exam.

3Q
the answer is not provided, what's going on?
The kindergartners and first and second graders were talking about their favorite field trips during the school year. One of the teachers, Ms. Brewer, turned the discussion into a math lesson, and the students conducted a survey. Each child wrote down on paper which trip was his or her favorite. (Note that many children named more than one field trip as their favorite.) The survey revealed that 55 wrote down the trip to the river, 48 indicated the trip to the police station, and 38 included the trip to the hardware store. The police station and the river were chosen on 32 papers, 26 papers included both the river and the hardware store, and 22 children wrote down the police station and the hardware store on their papers. Ms. Burke counted 17 papers that included all three and one that did not list any of the three trips. How many children were surveyed? How many children wrote down the river but not the police station? How many children did not list the hardware store?
