Answer:

Test statistic Z = 2.1097

Step-by-step explanation:

Step(i):-

Given that size of the sample 'n' = 160

Given that mean of the Population(μ) = 5.3pounds/square inch

The Standard deviation of the population(σ) = 0.6

Mean of the sample(x⁻) = 5.4

Level of significance =0.1

Step(ii):-

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{5.4-5.3}{\frac{0.6}{\sqrt{160} } }$

Z = 2.1097

Final answer:-

Test statistic Z = 2.1097

Answer:

$Worth = \$284258.1$

Step-by-step explanation:

Given

$Dimension: 7in\ * 3in\ * 1in$

$Value = \$1214/oz$ ---- value of Gold

Required

The worth of 1 gold bar

First, calculate the volume (n) of the gold bar

$n = 7in * 3in * 1in$

$n = 21in^3$

Next, calculate the weight of the gold bar using:

$w = 11.15n$

$w = 11.15 * 21$

$w = 234.15oz$

Multiply the value of Gold by the weight of the gold bar to get the worth of the gold bar.

$Worth =Value * w$

This gives:

$Worth = \$1214/oz * 234.15oz$

$Worth = \$1214 * 234.15$

$Worth = \$284258.1$
