It has been suggusted that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the length of stay of a trip for pre- and post-retirees. A sample of 686686 travelers were asked how long they stayed on a typical trip. The observed results of the study are found below. You may round all answers for this problem to the nearest hundredth.

With this information, construct a table of estimated expected values. Use two digits after the decimal.

Now, with that information, determine whether the length of stay is independent of retirement using α=0.01

(a) χ2=

Use as many digits after the decimal as possible.

(b) Find the degrees of freedom:

(c) Find the critical value:

Again, use as many digits after the decimal.

(d) The final conclusion is

A. We can reject the null hypothesis that the length of stay is independent of retirement and accept the alternative hypothesis that the two are dependent.
B. There is not sufficient evidence to reject the null hypothesis that the length of stay is independent of retirement.

what does it mean if "your answer is assumed to be rounded to the highest power possible?" How do I input my answer if it is 2.0198??

In a survey of 100 U.S. residents with a high school diploma as their highest educational degree (Group 1) had an average yearly income was $35,621. Another 120 U.S. residents with a GED (Group 2) had an average yearly income of $33,498. The population standard deviation for both populations is known to be $4,310. At a 0.01 level of significance, can it be concluded that U.S. residents with a high school diploma make significantly more than those with a GED?

Enter the test statistic - round to 4 decimal places.

Enter the P-Value - round to 4 decimal places.

Can you conclude that U.S. residents with a high school diploma make significantly more than those with a GED?

Sulfuric acid is the chemical produced in the United States with the highest volume of production. In one of the earliest processes used to make it, an ore containing iron pyrites (FeS2) is roasted (burned) with air. The following reactions take place in the roasting furnace: The gas leaving the reactor goes to a catalytic converter in which most of the SO2 produced is further oxidized to SO3: Finally, the gas leaving the converter passes through an absorption tower, in which the SO3 is absorbed in water to produce sulfuric acid (H2SO4). (a) An ore containing 82 wt% FeS2 and 18% inerts is fed to a roasting furnace. Dry air is fed to the furnace in 40% excess of the amount theoretically required to oxidize all of the sulfur in the ore to SO3, an FeS2 oxidation of 85% is obtained, with 40% of the FeS2 converted forming sulfur dioxide and the rest forming sulfur trioxide. Two streams leave the roaster: a gas stream containing SO2, SO3, 02, and N2, and a solid stream containing unconverted pyrites, ferric oxide, and inert material in the ore. Calculate the required feed rate of air in standard cubic meters per 100 kg of ore roasted and the molar composition and volume (SCMJ100 kg of ore) of the gas leaving the roasting oven.
