An auditor takes a random sample of 880880 invoices from the 9510 invoices relating to the activities of a company in 2019. The sample mean value of the sampled invoices was £126 and the sample standard deviation was £58. Find a 99% confidence interval for the mean value of all the invoices for 2019. Round to 3 decimal places The records of the company states that the total income from the 9510 invoices was £1150710. The auditor's sample evidence does not support this stated total. True or false? What is the probability, rounded to 3 decimal places, that the company's income does not exceed the value in the records?

In a planned study, there is a known population with a normal distribution, 4- 45, anda- 3. What is the predicted effect size (d) if the researchers predict that those given an experimental treatment have a mean of (a) 45, (b) 47, (c) 50, (d) 52, and (e) 42? For each part, also indicate whether the effect is approximately small, medium, or large. Show all equations and work.

During the nutrition research, the amount of consumed kilocalories per day was measured for 18 people - 10 women and 8 men. Results are as follows: Women: 2026, 1600, 1700, 1950, 1922, 1786, 1712, 1777, 2006, 1832; Men: 2170, 2557, 2384, 2427, 2334, 2228, 2161, 2459. Calculate a 90% confidence interval on the mean for women and men separately. Assume distribution to be normal. Round your answers to the nearest integer (e.g. 9876). Women: i Men: i
Construct a 90% Confidence Interval based on the following data: 45, 55, 67, 45, 68, 79, 98, 87, 84, 82.
Prices of basic commodities are often greatly affected by typhoons. During the aftermath of recent typhoon, the prices of tilapia were reported to have been sold at ₱20 – ₱25 more per kilogram at local wet markets. However, the price was back to its normal mean price at ₱100 per kilo one week after. If a random sample of 10 tilapia sales transactions from local wet markets have prices (in pesos per kilo) of 107, 115, 130, 95, 100, 105, 98, 116, 104, 100. Assuming that the tilapia prices are normally distributed, is there sufficient evidence to say that the mean price of tilapia in these markets is greater than ₱100? Use a 0.05 level of significance.

#13. A random sample of 20 health maintenance organization was selected. For each health maintenance organization, the co-pay (in dollars) for doctors office visit was recorded. The results are as follows. 33, 41, 39, 27, 47, 60, 58, 31, 47, 25, 41, 42, 50, 47, 32, 35, 50, 55, 46, 37 Under the assumption that co-pay amounts are normally distributed find a 90% confidence interval for the mean co-pay amount in dollars. Give the lower and upper limit of a 90% confidence interval. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places in round your answer to one decimal place. Lower limit: Upper limit:

I chose Option 1 for this week’s discussion post. I want to estimate the population mean number of times adults between the ages of 30 and 45 went to the grocery store in the last week. I spoke with 12 adults and asked them how many times they went to the grocery store in the last week. The results were 0, 2, 2, 7, 5, 1, 0, 3, 1, 1, 4, and 3. Now calculate a 95% confidence interval for the population mean. (Round to three decimal places)
