Answer:
The mass of the isotope Chromium-50 would be 2.685 grams in 61.8 grams of elemental Chromium.
Explanation:
Natural chromium () is composed of four stable isotopes:
(4.345 % abundance),
(83.789 % abundance),
(9.501 % abundance) and
(2.365 % abundance). We can obtained the total mass of the isotope Chromium-50 (
), measured in grams, by multiplying the mass of elemental chromium (
), measured in grams by percentage ratio (
), dimensionless. That is:
If we know that and
, then the mass of isotope Chromium-50 would be:
The mass of the isotope Chromium-50 would be 2.685 grams in 61.8 grams of elemental Chromium.
Based on the calculations, the value of the test statistic and p-value are equal to -2.1213 and 0.0169 respectively.
<u>Given the following data:</u>
- Standard deviation = 2.
- Sample mean = 19.4.
- Number of sample = 50.
- Hypothesized mean = 20.
Mathematically, the value of the test statistic can be computed by using this formula:
zₓ = -2.1213.
From the z-table, the p-value is given by:
P(Z < zₓ) = P(Z < -2.1213)
P(Z < -2.1213) = 0.0169.
Since the p-value is equal to 0.0169 less than α = 0.05, we would reject H₀ : µ equal to 20. Thus, we would conclude that µ < 20.
