Answer:
The answer is Rectangular
Step-by-step explanation:
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
