Given below are the sodium contents (in mg) for seven brands of hot dogs rated as "very good." 410 460 360 350 280 540 520 (a) Use the given data to produce a point estimate of μ, the true mean sodium content for hot dogs. (Round your answer to four decimal places.) μ = 417.1429 ✓ (b) Use the given data to produce a point estimate of o2, the variance of sodium content for hot dogs. (Round your answer to four decimal places.) ²821061.9881 X (c) Use the given data to produce an estimate of o, the standard deviation of sodium content. (Round your answer to four decimal places.) 0 = Is the statistic you used to produce your estimate of a unbiased? (Hint: See the discussion following Example 9.3.)
