In
hypothesis testing, one can only positively prove something by disproving the
null hypothesis. I this case, the null hypothesis is that there is no
relationship between eating frozen pizza and dangerous cholesterol levels.
<span> A p
value of a statistical summary (such as the sample mean difference between two
compared groups) indicates the probability that the null hypothesis is true.
Generally, a p value < 0.05 is usually taken to be statistically
significant, i.e. a 5% chance that the null hypothesis is true. In this case,
the relationship was find to be non-significant.</span>

Explanation:
Personal selling is when a salesperson interacts with potential buyers face-to-face with the intent of selling to them. The salesperson engaged the customer aiming to convince them to buy a product. Personal selling is mostly applied to sales promotions.
The personal selling technique is sometimes called face-to-face selling. Its success largely depends on the salesperson's interpersonal skills.
The total labor cost of variance is the difference of the two presented costs. The actual cost of production is presented below,
actual cost of production = $198,000
The other cost can be calculated through the equation,
cost of production = (3 hours/labor u)(($8/unit)(8,000) = $192,000
Thus, the total labor cost variance is approximately $6,000.
The export of crops from the New World to the Old World transformed European society mainly by improving the diets of the population, which consequently increased population growth.
<h3 /><h3>How did the colonization of the new world benefit Europe?</h3>
The discovery of America by European explorers made the place known as the New World, due to the fact that there were lands and riches that were used by Europeans for the crops and exploitation of precious metals for the enrichment of the European metropolis.
Therefore, the colonization of the New World made Europe rich through the exploitation of the resources of the conquered lands, increasing the supply of raw materials and reducing the scarcity of society.

μ = 183, σ = 20, n = 50. (Round your answers to 2 decimal places.)If the true mean is .9350 with a standard deviation of 0.0090
<h3>What is
standard deviation?</h3>
The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.
The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation. Standard deviation may be written as SD.
A random variable, sample, statistical population, data set, or probability distribution's standard deviation is equal to the square root of its variance.
