Answer:

The test statistic value is, z = 0.57.

The p-value of the test is 0.2843.

Explanation:

A one-sided, single mean z-test can be performed to determine whether the mean caloric intake increased from 2403.7 kcal/day or not.

The hypothesis is defined as:

H₀: The mean caloric intake did not increase, i.e. μ = 2403.7.

Hₐ: The mean caloric intake did increase, i.e. μ > 2403.7.

The information provided is:

$\bar x = 2453.7\ kcal/day\\n=100\\\sigma = 880\ kcal/day$

The z-statistic is:

$z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{2453.7-2403.7}{880/\sqrt{100}}=0.5682\approx0.57$

The test statistic value is, z = 0.57.

Compute the p-value of the test statistic as follows:

$p-value=P(Z>0.57)=1-P(Z$

*Use a standard normal table.

The p-value of the test is 0.2843.

Is the power of a political party determined by votes and money?

Firlakuza [10]

Absolutely! For instance, look at the Libertarian party's candidate during the 2016 election, Gary Johnson. Many people when they went to vote saw his name on the ballot, but did not have a clue who he was. This is because the Libertarian party does not have the members or the money to properly campaign against the Republican or Democrat party
