In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 23% of your total grade, each major test is worth 21%, and the final exam is worth 35%. Compute the weighted average for the following scores: 95 on the lab, 67 on the first major test, 72 on the second major test, and 76 on the final exam.
A U.S. magazine, Consumer Reports, carried out a survey of the calorie and sodium content of a number of diﬀerent brands of hotdog. There were two types of hotdog: beef, ’meat‘ (mainly pork and beef but can contain up to 15% poultry) and poultry. The results below are the calorie content of the diﬀerent brands of beef and poultry hotdogs. Beef hotdogs: 186,181,176,149,184,190,158,139,175,148,152,111,141,153,190,157,131,149,135,132 Poultry hotdogs: 129,132,102,106,94,102,87,99,170,113,135,142,86,143,152,146,144 Using six steps of hypothesis testing, determine if there is a strong evidence that the calorie content of poultry hotdogs is lower than the calorie content of beef hotdogs.

The owner of a chain of mini-markets wants to compare the sales performance of two of her stores, Store 1 and Store 2. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 10 days, chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below. 34 5 6 789 10 Day Store 1 Store 2 Difference (Store 1 - Store 2) Send data to calculator Check 1 454 381 73 2 446 808 975 404 835 275 754 341 42 -27 221 -66 399 7 809 246 263 703 336 759 (a) State the null hypothesis H and the alternative hypothesis H₁.

A new type of corn seed has been developed and a team of agronomists wanted to determine whether there was a significant difference between the types of soils that they are planted in (loam, sandy, salty, clay) based on the yield of the crop, the amount of water required, and the amount of herbicide needed.
