The heat evolved in calories per gram of a cement mixture is approximately normally distributed. the mean is thought to be 100, and the standard deviation is 2. you wish to test

h0: μ=100

versus

h1: μ≠100

with a sample of n = 9 specimens. a. if the acceptance region is defined as 98.5 ≤

x¯¯¯

≤ 101.5, find the type i error probability α. b. find β for the case in which the true mean heat evolved is 103. c. find β for the case where the true mean heat evolved is 105. this value of β is smaller than the one found in part (b). why?

To determine the number of deer in a forest a forest ranger tags 280 and releases them back

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
