One sample has ss=36 and a second sample has ss=24. A) if n= 5 for both samples, find each of the sample variances and compute the pooled variances. Because the samples are now the same size, you shoukd find that the pooled variances is exactly halfway between the two sample variances.
B) Now assume that n=5 for the first sample and n=13 for the first sample and n=13 for a second. Again, calculate, the two sample variances and the pooled variances. You should find that the pooled variance is closer to the variance for the larger sample

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

What is the measure of angle x? answer

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
