Zn + H₂SO₄ = ZnSO₄ + H₂

Zn⁰ - 2e⁻ = Zn²⁺  zinc is the reducing agent
2H⁺ + 2e⁻ = H₂    hydrogen ions is oxidizer

The answer is d)

Zn has oxidation number 0; Zn(2+) has oxidation number +2. Here 2 electrons were taken away, so the Zn was oxidized. So, the transformation requires an oxidizing agent.

The p-value of a statistical test depends on all of the following, except:
vaieri [72.5K]

Answer:

The correct option is e.

Explanation:

p-value is the probability value for a given statistical model, the probability that, when the null hypothesis is true.

For two two samples the formula of test statistics is

t=\frac{(\overline{x}_1-\overline{x}_2)-(\mu_1-\mu_2)}{\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}}

where,

\overline{x} is sample mean

\mu is population mean.

s is standard deviation.

n is sample size.

Variance is the square of standard deviation.

It means variance, mean, numbers of samples is used in calculation of p-value.

Degree of freedom define the shape of the t-distribution that your t-test uses to calculate the p-value.

d.f.=n_1+n_2-2

p-value of a statistical test depends on all of the following, except median.

Therefore the correct option is e.
