Draw 4) A study of dog obedience training was completed. 40 dogs were trained using the K9 Complete Program. It was found that their mean skill value increased by 1 points (on a 10 point scale) after participating in the 6-month program. Statistical analysis was used to find that the likelihood of these results by chance is 1 out of 1000. Use sentences to explain each answer below. a) Do these results have statistical significance? Yes or No (circle one choice) Explain why this data has or does not have statistical significance. b) Do these results have practical significance? Yes or No (circle one choice) Explain why this data has or does not have practical significance.

I AM RESUBMITTING THIS QUESTION FOR DIFFERENT PARTS. I AM AT THE SECOND NUMBER 2 QUESTION "P-VALUE =". Before the furniture store began its ad campaign, it averaged 160 customers per day. The manager is investigating if the average has changed since the ad came out. The data for the 16 randomly selected days since the ad campaign began is shown below: 131, 127, 148, 143, 141, 153, 158, 145, 138, 163, 164, 148, 166, 154, 170, 133 Assuming that the distribution is normal, what can be concluded at the αα = 0.05 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion The null and alternative hypotheses would be: H0:H0: ? μ p Select an answer < = ≠ > H1:H1: ? p μ Select an answer = > ≠ < The test statistic ? t z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > αα Based on this, we…
An investigator analyzed the leading digits from 791 checks issued by seven suspect companies. The frequencies were found to be 5, 13, 5, 68, 273, 358, 5, 23, and 41, and those digits correspond to the leading digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law shown below, the check amounts appear to result from fraud. Use a 0.01 significance level to test for goodness-of-fit with Benford's law. Does it appear that the checks are the result of fraud? Leading Digit Actual Frequency Benford's Law: Distribution of Leading Digits 1 3 4 5 6 7 8 9 13 5 68 273 358 5 23 41 30.1% 17.6% 12.5% 9.7% 7.9% 6.7% 5.8% 5.1% 4.6% Determine the null and alternative hypotheses. Но At least one leading digit has a frequency that does not conform to Benford's law. The leading digits are from a population that conforms to Benford's law. At least two leading digits have frequencies that do not conform…

A) Last week, Sarah had exams in math and in Spanish. On the math exam, the mean was 30 with a standard deviation of 5, and Sarah had a score of 45. On the Spanish exam, the mean was the mean was 60 with a standard deviation of 8, and Sarah had a score of 68. For which class should Sara expect the better grade? Math Spanish The grades should be the same because the two exam scores are in the same location There is not enough information to determine which is the better grade B) What proportion of a normal distribution is located between z = 0 and z = +1.50? 9332 0668 4332 8664 C) A two-way factorial study with two levels of factor A and three levels of factor B uses a group of n = 5 participants in each treatment condition.

A company conducted a survey on the number of hours employees spend on a particular task per week. The data collected from a sample of 10 employees are as follows: 5, 6, 7, 8, 9, 10, 10, 11, 12, 13. Calculate the standard deviation of the hours spent on the task per week.
In a large city, researchers selected a random sample of 120 individuals who have multiple televisions in their house connected to a streaming device. Each individual was asked how many hours of streaming content they watch in a typical week. The sample had a mean of 12.5 hours. For which of the following populations is 12.5 hours a reasonable estimate of the mean hours of weekly streaming content watched? (A) All individuals who regularly watch streaming content (B) All individuals from this city who regularly watch streaming content (C) All individuals from this city with multiple streaming devices in their house (D) All individuals from this city with multiple streaming devices in their house who regularly watch streaming content (E) All 120 individuals in this city with multiple streaming devices in their home who regularly watch streaming content

An investigator analyzed the leading digits from 794 checks issued by seven suspect companies. The frequencies were found to be 218, 130, 106, 83, 65, 48, 48, 37, and 59, and those digits correspond to the leading digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law shown below, the check amounts appear to result from fraud.

1. Jenny wants to compare the number of weight people lose at her gym using two popular, non-overlapping weight-loss programs, Shred-It and Burn It. She randomly samples people who use each program and tracks their weight loss. Shred It Burn It Mean 10 kg 7 kg Standard deviation 3.5 kg 5.7 kg Number of people 35 35 Determine if the mean weight losses are significantly different for the two programs. Assume that all conditions have been met.
Since the chi-square does not indicate the strength of the association, a researcher must then conduct a separate test for the measure of association. True False
