The tax return forms of a certain company contains many numerical values accounting for revenues and losses. 968001 of these numerical values begin with the digit 5. 999211 of these numerical values begin with the digit 6. Do we have any concerns about the authenticity of the data of these tax declarations? - Probably yes, further investigation is worth - Impossible to decide - Probably not, all looks reasonable
The level of a pollutant in the river next to a chemical factory is monitored at regular intervals. Over the course of years, the level of the pollutant was determined by chemical analysis. In recent years, the company has made some changes in the factory where increases in the pollutant level can be observed. The environmental protection organization (EPA) wants convincing evidence that the level of the pollutant has not increased. By creating the relevant null and alternative hypotheses, I. type and II. describe type errors.

Using data for the number of cases in the first quarter of 2022 from Table 1 (i.e., the final column) and the child population sizes in Table 2, create a table to show the incidence as percentages for each of the Health Trusts. Ensure that your table is clearly laid out with appropriate column headings, has an informative title, and that the values in your table are correctly rounded to two decimal places. You must also show one fully worked calculation underneath your table to demonstrate that you know how to perform these calculations, even if you used the Excel spreadsheet to derive your answers. State why it is important to report incidence as percentages or rates rather than as number of cases when comparing populations. Word limit: 100 words
Every 5 years a city conducts a survey of residents to collect data on various political, economic, an health indicators. With a new survey coming this year the mayor is especially concerned with jobs and the economy. In the last survey only 41% of people in the city said they felt very secure in their job. The mayor wants to be able to estimate that proportion for this year to within a margin of error of +/- 2%. How large of a sample will be needed.
Allison finds that the Pearson correlation coefficient for the relationship between number of pets owned and a person's IQ is +0.21. There are 25 people in her sample. Assuming an alpha level of 0.05 and a two-tailed test, what should she conclude? a. Reject the null hypothesis. The critical value is larger than the calculated value. b. Fail to reject the null hypothesis. The critical value is larger than the calculated value. c. Fail to reject the null hypothesis. The value is larger than the calculated value. d. Reject the null hypothesis. The calculated value is larger than the critical value.
Doritos chips are one of the most popular chips in the year 2020. Frito-Lay produces snack-sized bags of Doritos with 1.75-ounce bags. Unfortunately, Frito-Lay has received many complaints that the bags of chips lack the promised amount of chips. PepsiCo, the owner of Frito-Lay, decide to run an internal investigation of their Doritos chip production. They sample around 500 bags of chips to discover that they found an average of 1.59 ounces with a standard deviation of .12 ounces. Conduct a hypothesis test with an alpha-level of .05. Should they change their production of Doritos chips to match the 1.75 ounces on the bag?
Previous enrolment records at a large university indicate that of the total number of persons who apply for admission, 60% are admitted unconditionally, 5% are conditionally admitted, and the remainder are refused admission. Of 500 applicants to date for next year, 329 were admitted unconditionally, 43 were conditionally admitted, and the remainder were not admitted. Do the data indicate a departure from previous admission rates? Test using α = .05.a) State the hypotheses.b) Find the critical value at the 5% significance level (rounded off to four decimals).c) Calculate the value of the Chi-square test (rounded off to two decimals).d) State the conclusion at the 5% significance level.
