definitions
100
a normal curve must be bell-shaped
yes a normal curve must be bell-shaped otherwise it wouldnt meet the criteria of being a normal curve
100
in any normal or standard distrubution x is always the symbol standing for.....
x is always the symbol in any normal or standard distribution for the mean...
100
a normal curve is bell-shaped
true any normal curve must be bell-shaped otherwise it would not meet the criteria of being a normal curve
100
what do the symbol n mean in a binomial distribution
in a binomial distribution the symbol n means the number of sucesses
100
a symmetrical frequency distribution curve
normal distribution
200
when exanmining over a period of equally spaced time intervals or in some sequential order, is control charts useful
yes control charts are useful when exaniming over a period of equally spaced time intervals or in some sequential order.
200
it is symmetrical about thr vertical line through the mean.. this would be a property of....
this is a property of a normal curve
200
a normal curve must not be symmetrical
false a normal curve must be symmetrical
200
in a binomial distribution the symbol r means
the symbol r would mean in a binomial distribution the number of sucesses
200
a widely used measure of variability or diversity used in statistics and probability theory
standard deviation
300
approxmately 99.7% of the data values will lie within one standard deviation on each side of the mean
no due to the empirical rule approxmately 68% of the data values will lie within one standard deviation on each side of the mean NOT 99.7%
300
approxmately 95% of the data values will lie within two standard deviations on each side of the mean..... this is true due to the ....
the statement is a fact due to the EMPIRICAL RULE
300
normal curves are symmetrical with a z peek
false normal curves are symmetrical but they are bell shaped not with a z peek
300
dealing with a binomial distribution what do the symbol q mean
the symbol q means the probability of sucess
300
indicates upper and lower control limits and often include a central (average) line
control charts
400
using the normal distribution table as z values increase, do the areas to the left increase
yes in using a normal distrbution table as z values increase, so do the areas to the left increase
400
in a binomial distribution np stands for ....
number of trails x number of suceesses
400
tails of a normal curve gets closer to the x axis and then go away
false tails of a normal curve gets closer to the x axis but not go away
400
when you take the product of np in a binomial distribution what is that equal to be
when you take the product of np it would be equal to be the MEAN in a binomial distribution
400
a discrete probability distribution of the number of successes in a sequence of n independent yes/no experiments
binomial distribution
500
is the mean under the peak of the normal curve
yes the mean is always under the peak of a normal curve
500
used for examining data over a period of time
control charts are used for examining data over a period of time
500
tails of a normal curve get closer to the horizontal axis but it never touches it or crosses it
true
500
taking the product of npq and square rooting it you will end up with
in a binomial distribution when you take the product of npq and square root it you will end up with the STANDARD DEVIATION
500
states that for a normal distribution nearly all values lie within 3 standaed deviations of the mean also know as the three sigma rule
empirical rule
