Question

Certain mineral elements required by plants are classed as macronutrients. Macronutrients are measured in terms of their percentage of the dry weight of the plant. Proportions of each element vary in different species and in the same species grown under different conditions. One macronutrient is sulfur. In a study of winter cress, a member of the mustard family, these data, based on three independent random samples, are obtained:

Answer 1

The value of μ will be "0.82".

Explanation:

The given question is incomplete. Please find attachment of the complete question below.

The given three random samples are 0.8, 0.95 and 0.7.

Now,

⇒
`\mu=\frac{\bar{x_1}+\bar{x_2}+\bar{x_3}}{3}`

On substituting the estimated values, we get

⇒
`=(0.8+0.95+0.7)/(3)`

⇒
`=(2.45)/(3)`

⇒
`=0.82`

It will not rational here, considering the equivalent significance, since the sampling amount for sample 3 becomes somewhat big 200.
