Arsenic is an element that occurs naturally in groundwater, but a mean greater than 8.0 parts per billion indicates that the gro

Studentka2010 [4]

Answer:

Based on the data, if we find moderate/strong evidence against the null hypothesis and conclude the mean arsenic level of the water is greater than 8.0 ppb, we have made ____________.

a correct decision.

Step-by-step explanation:

Since there is enough evidence to conclude that the mean level of arsenic is greater than 8.0 ppb, the correct decision has been made. There is no type I or type II error. The type I error (called a false positive) occurs if we reject the null hypothesis when it is true. Since we have simply rejected the null hypothesis when the alternate hypothesis is true, and the null hypothesis should be rejected, a correct decision has been made.

Jerry hears 5 case ever 2 3/8 hours Jerry hears a constant rate how many case does Jerry hear per hour

irakobra [83]

Answer:

The rate of cases is $\frac{40}{19}$ per hour

Step-by-step explanation:

we are given

Total number of cases =5

total time is

$=2\frac{3}{8}$ hour

we can simplify it

total time is

$=\frac{2\times 8+3}{8}$ hour

$=\frac{19}{8}$ hour

we can use formula

rate of cases = ( total number of cases)/( total time)

now, we can plug values

Rate of cases is

$=\frac{5}{\frac{19}{8} }$

$=\frac{40}{19}$
