FOOD For Exercises $20-23$ , use the following information. The shelf life of a particular snack chip is normally distributed with a mean of 180 days and a standard deviation of 30 days.
About what percent of the products last less than 90 days?
So were asked here to find the average of January, September and October to January, September in October. Let's see, January was negative. 19.3, September was 27.0 and October was 8.8. And so we're gonna add those up, and then we're gonna divide by three to find the average. And so the 1st 2 I'll do a little side problem. 27 0.0 minus 19.3. Gotta borrow from the seven to make it a sick some 10 minus 37 six minus nine Doesn't work so far from that to make it 16 minus nine, which is seven. So it looks like we've got a difference of 7.7. So when I had those up, I have 7.7 plus 8.8. Let's do another little side problem. 7.7 plus 8.8 15 carry the warm. So 16.5, modifying the average of two divided by three. Cause they were three months, 16.5 divided by three. And that looks like 5.5. That's it
A problem. 21 in Excel 1919 a n B. We determined the average now actually looted preacher with and without always ways and the recent posts Tito approximately able to 6.42 degrees and he and actually without with weights, is approximately equal to 6.40 19.
So our goal is to represent this data accurately. Um and we're going to have 12 points as a result because there's a point for every month that we have in the year. This is March april Okay, me and why? August september october november summer. Now we want to plug in all the individual values. We have 67 mm 12 18. Then we have 24 28 31 29. So we have 24 28 31 you know? And then 26 1913 7. Okay. Zooming out. Looking at our values. We want to see what this graph looks like and we see that the value is rising until it reaches the middle of the year and then it starts to come down. So that's the graph that we see.
I have a problem. Number 20 in exercise 19 A and B we determined the average monthly high temperature with and without weights. James D. Hi. It's approximately equal to 18 0.42 Thank and T that I approximately is ableto 18.49 degrees.
