### Step 2**(b) Which of the two intervals conveys more precise information about the value of the population proportion?**Recall that a smaller standard error of $ p $ results in a narrower confidence interval. A narrower confidence interval is then more precise.The width of Interval 1, (0.27, 0.35), is $ 0.35 - 0.27 = \_\_\_\_\_\_\_$ , and the width of Interval 2, (0.30, 0.34), is $ 0.34 - 0.30 = \_\_\_\_\_\_\_$ . Therefore, \[ \_\_\_\_\_\_\_\_\_, \] is the narrower and more precise interval.[Submit] [Skip (you cannot come back)]

Suppose researchers are about to draw a sample of 1500 observations from a normally distributed population, and use this data to create a confidence interval for the population mean using the t procedure. They don't know much about statistics, and decide to use a ta/2 value of 0.46 to calculate the margin of error. (Since, curiously, that is their favourite number.) What is the confidence level of this confidence interval? Express your response as a percentage, but do not include the percent sign. e.g. If the confidence level is 87.6%, then enter 87.6. (Give your numeric response to at least 1 decimal place. Give only your numeric response, and not any extra characters or symbols.)
HELP WITH BOTH QUESTIONS THAT GO WITH PICTURE.. Question 1: What is the confidence interval for the population mean μ? _____hg <μ<_____ hg (Round to one decimal place as needed.) Question 2: Are the results between the two confidence intervals very different? A. Yes, because the confidence interval limits are not similar. B. Yes, because one confidence interval does not contain the mean of the other confidence interval. C. No, because each confidence interval contains the mean of the other confidence interval. D. No, because the confidence interval limits are similar.
Find a 90% confidence interval for the population mean age of the Smurfs if a sample of 52 smurfs have a mean age of 49.7 years. The standard deviation is know to be 3.4. The Margin of Error (3 decimals) is E = . The answer is We are 90% confident the true mean age of Smurfs is between and years.

While finding a confidence interval of the population mean (µ), the confidence interval a. shrinks as the sample size goes up. b. expands as the confidence level goes up. c. expands as the sample standard deviation goes up. d. all the above are true.
In the estimation of the population mean, what if given that last year mean is 7.05 and SD is unknown, and this year the sample mean given is 7.2. Should I use 7.05 or 7.2 in my calculation for confidence interval
An analyst constructed a confidence interval for the amount of product yielded in a batch run by taking a sample of 900 batches. Over the 900 batches, the average yield was 100 grams and the yield standard deviation was 8 grams. If the 95% confidence interval for the true average yield is (100–x , 100+x) grams, calculate x. Round your answer to three decimal places.
It took an average of 4.4 years for a grove of 57 orange trees to bear fruit. Assume the standard deviation of the population is o = 3.7 years. Construct a 96% confidence interval. Round your answers to two decimal places. The lower limit of the confidence interval is and the upper limit is
It is known that the population mean for the verbal section of the SAT is 500 with a standard deviation of 100. In 2006, a sample of 400 students whose family income was between $70,000 and $80,000 had an average verbal SAT score of 511. The point estimate of the mean for this group is 511 and the 95 confidence interval for this group is?
