16. Credit Card Use by Undergraduates. In a study entitled How Undergraduate Stu-dents Use Credit Cards, it was reported that undergraduate students have a mean creditcard balance of $3173. This figure was an all-time high and had increased 44% overthe previous five years. Assume that a current study is being conducted to determineif it can be concluded that the mean credit card balance for undergraduate students hascontinued to increase compared to the original report. Based on previous studies, use apopulation standard deviation ơ = $1000.a. State the null and alternative hypotheses.b. What is the p-value for a sample of 180 undergraduate students with a sample meancredit card balance of $3325?c. Using a .05 level of significance, what is your conclusion?

From the provided information, Population mean (µ) = $3173 Standard deviation (σ) = $1000 The claim…

According to a dietary study. high sodium in take may be related to ucers. stomach cancer. and migraine headaches. The human requirement for salt is only 220 milligrams per day. which is surpassed in most single servings of ready-to-eat cereals. If a random sample of 20 similar servings of a certain cereal has a mean sodium content of 244 milligrams and a standard devlation of 24.5 miligrams, does this suggest at 0.05 level of significance that the average sodlum content for a single serving of such cereal is greater than 220 milligrams?

Part II. Complete the ANOVA table below using the study description. Answer the questions to determine if there is in fact a significant difference between the three groups. A psychologist would like to examine the effects of sugar consumption on the activity level of preschool children. Three samples of children are selected with n = 5 in each sample. One group gets no sugar, one group gets a small dose, and the third group gets a large dose. The psychologist records the activity level for each child. The data from this experiment are presented below. 1. Do these data indicate any significant differences among the three groups? Test with α = .05.
A consumer response team hears directly from consumers about the challenges they face in the marketplace, brings their concerns to the attention of financial institutions, and assists in addressing their complaints. The consumer response team accepts complaints related to mortgages, bank accounts and services, private student loans, other consumer loans, and credit reporting. An analysis of complaints over time indicates that the mean number of credit reporting complaints registered by consumers is 3.95 per day. Assume that the number of credit reporting complaints registered by consumers is distributed as a Poisson random variable. Complete parts (a) through (d) below. a. What is the probability that on a given day, no credit reporting complaints will be registered by consumers? = 0.0193 b. What is the probability that on a given day, exactly one credit reporting complaint will be registered by consumers? = 0.0761 c. What is the probability that on a given day, more…

Asian Americans are a heterogeneous group often coined as one in national and state estimates of health data. Recent studies, however, have shown that some Asian American subgroups are more likely to die early due to cardiovascular disease and more likely to report metabolic syndrome. An epidemiologist wants to study the age of diagnosis of type 2 diabetes among two Asian American subgroups (Asian Indians, Koreans). The researcher had the following two questions: Is the mean age of diagnosis for type 2 diabetes among Asian Indians different than 55 years? Is the mean age of diagnosis of type 2 diabetes different between Koreans and Asian Indians? The epidemiologist should conduct which types of tests to answer the above 2 questions? None two-sample t test after checking for equal variance and a one sample t-test One-sample t test and two-sample t test after checking for equal variance One-sample t test and ANOVA One-sample t test and ANOVA
The Transportation Security Administration (TSA) collects data on wait time at each of its airport security checkpoints. For flights departing from Terminal 3 at John F. Kennedy International Airport (JFK) between 3:00 and 4:00 PM on Wednesday, the mean wait time is 12 minutes, and the maximum wait time is 16 minutes.

The Energy Star rating system is an energy efficiency program run by the U.S. Environmental Protection Agency (EPA)Energy Star certified appliances, such as televisions and refrigerators, are rated in regard to their average energy consumption per year. A certain brand of Energy Star certified refrigerator is stated to have a mean yearly electricity cost of $99. A consumer advocacy organization believes that this claim is wrong, that the energy consumption of this particular refrigerator is different than $99 per year. The group collected a random sample of 16 refrigerators of the model in question and had each lab-tested for electricity consumption. The yearly energy consumption of each is given below. 96.7697.898.67 95.52 97.8 95.896.9299.57 97.64 95.46 98.03 96.42 99.32 98.99 95.2197.12 Using alpha = 0.1 , test the hypothesis that the average yearly electricity consumption of the refrigerator in question is different than $99 per year. Assume that the distribution of all electricity…
