    a good strategy that will help small businesses is sales. I say sales, because what individual does not like a discounted price? Not only will the sale price change, but also the customers will increase in number. The more customers the more products will decrease in the store. I once worked at a smaller business, until we got out of business. On this job, we was not making enough sales to keep the business up and going. With this being said, we ended up having to put the whole store on sale. No, I am not saying go and put everything on sale to help a small business, because you will be setting your business up for failure. I am saying with a small business, sales can help the business bring in more customers. Most small businesses provides sales, by weekly ads. In these ads, they have particular items on sales for that particular week. The business itself be packed with customers due to them trying to catch last minute sales.

    Since this pandendemic started with Covid 19 new strategies have started to keep businesses open. It has been really hard to think of new working strategies that will work for the public and businesses. The new strategy of online orders has been a great idea that has been a working strategy that many are now suing. I think if this idea had not come a long a lot of businesses would have lost their business. This technique has increased sales and has gained new business for many type of companies. Online orders especially more now than ever have been used by consumers. Due to Covid 19 businesses have been trying many ways to stay in business and this has been a really helpful tool to use and inform consumers about. Consumers can use the many apps available for most businesses in the world to do many things like pay orders, make orders, leave ratings, etc. I find myself using this tool quite often throughout my daily living. I am sure many individuals also use this tool from time to time.

    PSY 223 Milestone Three Worksheet

    Review the critical elements that must be addressed in the final project. Use this worksheet to create Milestone Three. A
    hypothesis is a position about research outcomes. In this assignment, you will describe two hypotheses associated with your research scenario.

    Points to consider:

    A researcher acts like the coach of a sports team. In a pregame meeting, a coach describes the possible scenarios associated with outcomes of a game. “If we win, it means we go to the playoffs; if we lose it means our season is over.” The coach’s specificity helps ensure everyone is clear on what the team is up against and what is at stake.

    Before doing an analysis, researchers do something similar. They acknowledge potential outcomes of the upcoming analysis. “We can find either: (a) variation in the data reflects chance, or (b) variation in the data is due to a systematic law.”

    Researchers call position (a)
    null hypothesis (symbolized
    H0). Researchers call position (b)
    alternative hypothesis (symbolized
    Ha). A researcher customizes the hypotheses to a study, using symbols and information about the specific study.

    1. Indicate your research hypotheses (null and alternative), incorporating the appropriate symbols. [
    To answer this question, you need, in part, to look at the research scenario.]

    2. State what the hypotheses mean. [
    Some overlap may exist with your answer to # 1. These are related rather than mutually exclusive questions.]
