Gaynor Advertising conducted a survey to determine individual’s main source of news as well astheir educational level. 2500 individuals were surveyed and the results are given in the attached table.
a. State both the null and alternative hypotheses. b. Provide the decision rule for making this decision. Use an alpha level of 5%. c. Show all of the work necessary to calculate the appropriate statistic. d. What conclusion are you allowed to draw? e. Would your conclusion change at the 10% level of significance? f. Confirm test results in part (c) using JASP
Determine the first step of hypothesis testing, and explain the procedure and logic of this step. Choose the correct answer below.
A.
The first step is to determine the level of significance at which to conduct the hypothesis test. The conventional levels of significance used are 5% and 1%, which are described as the 0.05 significance level and the 0.01 significance level, respectively. When a sample score is so extreme that researchers reject the null hypothesis, the result is said to be statistically significant.
B.
The first step is to restate the question as a research hypothesis and a null hypothesis about the populations. Since researchers are interested in the results in terms of the population, it is useful to restate the research question in terms of populations. The research hypothesis represents the research question being asked.
C.
The first step is to determine the characteristics of the comparison distribution. The overall logic of hypothesis…
DIRECTIONS: Identify the appropriate hypothesis test for each of the following research situations labeled (a) - (d). Make
sure to label your responses clearly!
a. A researcher wants to see whether that is a significant difference people who sleep 4 hours per day and those who sleep
8 hours per day their work productivity.
b. A researcher conducts a study to examine the relationship between happiness level and number of hours a kid spend
time with their parents during summer time.
C. A researcher would like to determine whether a nutrition milk will benefit for 6 months baby, a group of n=100 6
months baby is measured about their healthy level before and after nutrition milk is provided
d. A researcher would like to determine whether there is a significant different between 2 months, 4 months and 6 months
