Hi, please help me A garage band wants to hold a concert. The expected crowd has a Normal distribution with the mean of 3000 and standard deviation of 200. The average expenditure on concessions is Uniformly distributed with a minimum of $10 and maximum of 25 dollars. Tickets sell for $10 each, and the band’s profit is 80% of the gate (ticket sale) and concession sales, minus a fixed cost of $12,000. Use the provided spreadsheet model and conduct a Monte Carlo simulation with 500 trials to analyze the band profit.
In your analysis,
a. find the minimum, maximum, average, and standard deviation for band profit.
b. create the frequency distribution (using FREQUENCY function) and the histogram for
band profit.
c. Find the probability that band profit will be greater than $62000.

Reliability and validity reliability and validity are two important considerations that must be made with any type of data collection. reliability refers to the ability to consistently produce a given result. in the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. to illustrate this concept, consider a kitchen scale that would be used to measure the weight of cereal that you eat in the morning. if the scale is not properly calibrated, it may consistently under- or overestimate the amount of cereal that’s being measured. while the scale is highly reliable in producing consistent results (e. g., the same amount of cereal poured onto the scale produces the same reading each time), those results are incorrect. this is where validity comes into play. validity refers to the extent to which a given instrument or tool accurately measures what it’s supposed to measure. while any valid measure is by necessity reliable, the reverse is not necessarily true. researchers strive to use instruments that are both highly reliable and valid.
