A study was recently conducted to estimate the mean cholesterol for adult males over the age of 55 years. The following random sample data were observed: 245 304 135 202 300 196 210 188 256 390 Given this information, what is the point estimate for the population mean? Question 2 options: About 242.6 ±102 About 73.35 Can't be determined without knowing the confidence level.

Respuesta :

Answer: point estimate = 242.6

Step-by-step explanation:

From the information given,

Number of adults sampled = 10

Mean = sum of the ages/number of adults sampled

Mean = (245 + 304 + 135 + 202 + 300 + 196 + 210 + 188 + 256 + 390)/10 = 242.6

The sample mean is the point estimate for the population mean

The confidence level is required to determine the margin of error between the point estimate and the population mean
