There are 505 full-service restaurants in North Dakota. The mean number of seats per restaurant is 74.1. [Source: Data based on the 2002 Economic Census from the US Census Bureau.] Suppose that the true population mean µ = 74.1 and standard deviation σ = 21 are unknown to the North Dakota tourism board. They select a simple random sample of 45 full-service restaurants located within the state to estimate µ. The mean number of seats per restaurant in the sample is M = 78.3, with a sample standard deviation of s = 17.8.

The standard deviation of the distribution of sample means (that is, the standard error, σM

M

) is . (Note: Although µ and σ are unknown to the North Dakota tourism board, they are known to you for the purposes of calculating these answers.)

The standard or typical average difference between the mean number of seats in the 505 full-service restaurants in North Dakota (µ = 74.1) and one randomly selected full-service restaurant in North

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
