Dear Tutor, I am trying to figure out how to
Question Dear Tutor, I am trying to figure out how to fit a curve to my data using MS excel solver. The graph is a frequency distribution histogram with time on the x axis split into 5 minute bins and the number of jobs in each bin on the y axis. I am pretty certain that the data is some kind of log normal distribution. BIn Frequency5 010 015 120 425 330 835 1140 945 250 755 660 365 3What I want to do is to find a fitted distribution using the lognormal formula and put in “adjustable” constants.I then want to deduct the sample frequencies from the fitted frequencies to get residuals. I will then take the sum of the squared residuals and place it on the screen at the bottom of the squared residuials column.. Finally, I want to square the residuals (to yield all positive numbers).Then, I call up Solver. I enter my x values and my adjustable constants (mean, sd and cumulative) press “solve” and I should get a curve that is close to my estimate. Except that I don’t. I am having trouble generating a “fitted” data column since I am not sure how to write out to lognormal funtion in excel – I just can’t seem to get it right after three days of trying Help…..

Question In an advertising campaign, a snack company claimed that every 18-ounce bag of its cookies contained at least 1000 chocolate chips. Two statisticians attempted to verify the claim. The accompanying data represent the number of chips in an 18-ounce bag of the company’s cookies based on their study. Complete parts (a) through (e). Click here to view the chocolate chip data table.

Enter = followed by the regression formula. Enter the intercept and slope into the formula by clicking on the cells in the regression output with the results. *I used (103.27*37) 37 = 3858-Is this correct?* Is it appropriate to use this data to predict the amount of time that a 68-year-old will be on the Internet? Yes (is this correct?) If yes, what is the amount of time, if no, why? I used (103.27*68) 68-Is this correct?Thank you, and let me know if you need more info

Identify a time dependent variable in any kind of organization,
Question Identify a time dependent variable in any kind of organization, business, or industry. Collect several measurements of this variable over time. Draw a scatter diagram of this variable versus time. What are your observations? Is there a trend in the measurements? Explain. Are there any seasonal variation in the measurements? Explain. Add a trend line to the scatter diagram, and determine the trend equation. Interpret the trend equation. Purpose: To demonstrate the application of time series analysis in your organization, business, or industry. Example: John works for an electric utility company. Over the years the demand for electricity has been growing constantly. The electricity demand measured in Megawatts is an example of a time dependent variable. When a scatter diagram of electricity demand versus time is plotted, there is an upward trend and seasonal variation. The upward trend is the result of growing demand over time. The electricity demand is high during the summer season, and is low during winter season. This pattern is repeated year after year.
