Answer:

$\bar{x}=61.98$

Step-by-step explanation:

The sample mean $\bar{x}$ is a point estimate of the population mean μ.

Given the heights of the 6 tomato plants sample below:

55.6, 59.4, 59.9, 62.9, 64.9, 69.2

Point Estimate,

$\bar{x}=\dfrac{55.6+59.4+59.9+62.9+64.9+69.2}{6} \\=\dfrac{371.9}{6} \\\bar{x}=61.98$

Whales head : 1/3(100) = 100/3 = 33.33 ft or 1/3(30) = 30/3 = 10 meters
new baby whale : 1/4(100) = 100/4 = 25 ft. or 1/4(30) = 30/4 = 7.5 meters
average man height : 1/17(100) = 100/17 = 5.88 ft or 1/17(30) = 30/17 = 1.76 m
average man weight : 1/1818(300000) = 300000/1818 = 165 lbs or 1/1818(136000) = 136000/1818 = 74.81 kilograms
human baby height : 1/4(5.88) = 5.88/4 = 1.47 ft or 1/4(1.76) = 0.44 meters
