Researchers are interested in the effect of a certain nutrient on the growth rate of plant seedlings. Using a hydroponics growth procedure that utilizes water containing the nutrient, they planted six tomato plants and recorded the heights of each plant 14 days after germination. Those heights, measured in millimeters, were as follows: 55.6, 59.4, 59.9, 62.9, 64.9, 69.2 What is the point estimate for the population means?

Respuesta :

Answer:

[tex]\bar{x}=61.98[/tex]

Step-by-step explanation:

The sample mean [tex]\bar{x}[/tex] 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,

[tex]\bar{x}=\dfrac{55.6+59.4+59.9+62.9+64.9+69.2}{6} \\=\dfrac{371.9}{6} \\\bar{x}=61.98[/tex]
