A researcher hypothesizes that there is the number of times a family gets takeout for dinner every month is not different by race/ethnicity. Suppose that Table 2 shows the results of her survey. White Black Hispanic Asian 16 12 8 8 12 4 8 8 12 12 12 10 16 12 4 16 16 8 Assume that all distributions are normal, the four population standard deviations are approximately the same, and the data were collected independently and randomly. Use a level of significance of 0.10. (HINT: Run an ANOVA: Single Factor) a. The alternative hypothesis (Ha) would be "At least one of the race/ethnicities has a different mean for their takeout per month habits." (Write "True" or "False" in the blank): b. What is the value of the F-statistic that you obtained using the data? (Round to three decimal places). c. What is the value of critical F for this table? (Round to three decimal places). d. What is your final decision? (Write "Reject Ho" or "Fail to reject Ho" in the blank):

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
