What is an interval in math term?
An interval is a subset of an order-numbered set; the interval includes a highest- numbered member of the subset and a lowest-numbered member of the subset and all members of the set with order numbers with values between that of the highest- and lowest-numbered members. This is more exactly called a "closed interval". An "open interval" is defined in the same way, except that the lowest-numbered and highest-numbered limits are not part of the subset.
Is date of birth ordinal or interval?
Date of birth is considered a ratio variable, not ordinal or interval. While it can indicate order (when someone was born before or after another), it also has a true zero point (the start of the calendar) and allows for meaningful comparisons of differences in age. This distinguishes it from ordinal (which only indicates order) and interval (which lacks a true zero) scales.
What must be present in order to use the z-interval procedure?
Use ZInterval when you have a single variable to analyze, and you already know the standard deviation
Interval estimation of the parameters of poisson distribution?
n order to fit the Poisson distribution, we must estimate a value for λ from the observed data. Since the average count in a 10-second interval was 8.392, we take this as an estimate of λ (recall that the E(X) = λ) and denote it by ˆλ.
