Britannia metal is composed of tin (Sn), antimony (Sb), and copper (Cu), with a known standard deviation for the antimony content to be ±0.7%. If six samples were measued and found to have the following antimony content, what is the 95% confidence interval for the population's expected mean? (Omit the mean from your answer, report the interval only, without the +/- to two decimal places). Sample 1: 6.04% Sample 2: 6.01% Sample 3: 5.94% Sample 4: 6.07% Sample 5: 5.98% Sample 6: 5.94%

From a sample with n=36, the mean duration of a geyser's eruptions is 3.06 minutes and the standard deviation is 0.85 minutes. Using Chebychev's Theorem, determine at least how many of the eruptions lasted between 1.36 and 4.76 minutes. At least of the eruptions lasted between 1.36 and 4.76 minutes. (Simplify your answer.)
The brain volumes (cm³) of 20 brains have a mean of 1087.8 cm³ and a standard deviation of 127.5 cm³. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1362.8 cm³ be significantly high? Significantly low values are (Type an integer or a decimal. cm³ or lower. Do not round.)
The brain volumes (cm³) of 20 brains have a mean of 1106.7 cm³ and a standard deviation of 126.2 cm³. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1309.1 cm³ be significantly high? Significantly low values are (Type an integer or a decimal. cm³ or lower. Do not round.) Significantly high values are cm³ or higher. (Type an integer or a decimal. Do not round.) Is 1309.1 cm³ significantly high? OA. Yes, because it is below the lower limit separating value. B. No, because it is above the upper limit separating value. OC. Yes, because it is between the limits separating values. O D. No, because it is between the limits separating values. OE. Yes, because it is above the upper limit separating value. OF. No, because it is below the lower limit separating value. ~
A study found that a 95% confidence interval for the mean μ of a particular population was computed from a random sample of 1200 people and found it to be 10 ± 4. Therefore, we may conclude:
An IQ test is designed so that the mean is 100 and the standard deviation is 9 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 95 percent confidence that the sample mean is within 2 IQ points of the true mean. Assume that o? = 81 and determine the required sample size.

What is the probability that the sample mean will be within 18 of the population mean (to 4 decimals)? b. What is the probability that the sample mean will be within 16 of the population mean (to 4 decimals)?
The population of weights of a particular fruit is normally distributed, with a mean of 248 grams and a standard deviation of 26 grams. If 11 fruits are picked at random, then 3% of the time, their mean weight will be greater than how many grams? Round to the nearest gram.
The brain volumes (cm³) of 20 brains have a mean of 1093.1 cm³ and a standard deviation of 120.6 cm³. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1284.3 cm³ be significantly high? Significantly low values are cm³ or lower. (Type an integer or a decimal. Do not round.) Significantly high values are 0cm³ (Type an integer or a decimal. Do not round.) Is 1284.3 cm³ significantly high? cm³ or higher. OA. Yes, because it is above the upper limit separating value. OB. No, because it is between the limits separating values. O C. No, because it is above the upper limit separating value. O D. Yes, because it is between the limits separating values. OE. Yes, because it is below the lower limit separating value. OF. No, because it is below the lower limit separating value.
