Which of the following statements are true? 1. Glass is mostly silicon dioxide and so when a long narrow glass tube is placed into water, the water molecules form adhesive forces with the oxygen atoms in the molecules of the glass 2. The Shape of the meniscus seen when water is poured into a glass container is due to cohesive forms being greater than the adhesive forced being experienced. 3. When a glass tube is placed into a dish of...

Which of the following statements are true? Note that there may be more than one correct answer; select all that are true. In order for the inference procedures for proportions to be valid, the population from which the random sample is drawn must be normally distributed. As the desired margin of error decreases, then the required minimum sample size will increase. When determining the minimum sample size, if the value of p^ is not given, we should use the "worst-case...
