Let x represent the height of first graders in a
class. This would be considered what type of variable:
Continuous
Lagging
Discrete
Nonsensical
Continuous Variable
A variable is said to be continuous if it can assume an infinite number of real values and since the heights of these could fall anywhere between a range of values and As a general rule, counts are discrete and measurements are continuous.

Let x represent the inches of rain on crops in Akron, Ohio. This would be considered what type of variable: A. Discrete B. Inferential C. Continuous D. Distributed
Determine whether the random variable x is discrete or continuous. Explain. Let x represent the number of hits to a website in a day. Choose the correct answer below.
Can height be a discrete random variable? For example, would height be considered a discrete variable if it was the height of basketball players listed in a program? (Since it is most likely rounded to one decimal place)
In a survey of first graders, their mean height was 50.4 inches with a standard deviation of 3.55 inches. Assuming the heights are normally distributed, what height represents the first quartile of these students? 48.01 inches 46.84 inches 43.30 inches 52.79 inches
In a survey of first graders, their mean height was 49.9 inches with a standard deviation of 3.15 inches. Assuming the heights are normally distributed, what height represents the first quartile of these students? 46.75 inches 47.77 inches 52.02 inches 43.60 inches
conducts an experiment in which they tip a coin 10 times and count of heads. Let the random represent varlable X represent the number of heads. Write the distribution of x In a class of 40 students, each student conducts an experiment in which they flip a coin 10 times and count the number of heads. Let the random variable&represent the mean number of heads found by the students Write the distribution of á 8) One student conducts an experiment...
Decide whether the random variable x is discrete or continuous. Explain your reasoning. Let x represent the temperature of a person taken with a mercury thermometer. Is the random variable x discrete or continuous? Choose the correct answer below A. Continuous, because x is a random variable that cannot be counted. B. Discrete, because x is a random variable that can be counted.
There are 218 first graders in an elementary school. Of these first graders, 86 are boys and 132 are girls. School wide, there are 753 boys and 1063 girls. The principal would like to know if the gender ratio in first grade reflects the gender ratio school wide. a. identify the hypothesis b. what are the degrees of freedom c. complete this table in SPSS and paste the output below to replace it: (how do you set this up in...
Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with μ=24.7 ft and σ=54 ft. You intend to measure a random sample of n=229 trees. What is the mean of the distribution of sample means? μ¯x= What is the standard deviation of the distribution of sample means (i.e., the standard error in estimating the mean)? (Report answer accurate to 2 decimal places.) σ¯x=
Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with μ = 148.6 ft and σ = 67.9 ft. You intend to measure a random sample of n = 193 trees. What is the mean of the distribution of sample means? μ ¯ x = What is the standard deviation of the distribution of sample means (i.e., the standard error in estimating the mean)? (Report answer accurate to 2...
