A swine producer wants to know if the average weight of his pigs is different from the breed average of 230 lb. He selects a ran
Aloiza [94]

Answer: t= -1.60

Explanation:

Let \mu be the population mean weight of pigs.

As per given , we have

H_0:\mu=230

H_0:\mu\neq230

Sample size : n= 16

Sample mean =\overline{x}=220\ lb

Sample standard deviation : s=25\ lb

<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>

Test statistic for population mean : t=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}

t=\dfrac{220-230}{\dfrac{25}{\sqrt{16}}} (Substitute all the values.)

t=\dfrac{-10}{\dfrac{25}{4}}

t=\dfrac{-40}{25}=-1.60

Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60

Why the dates on the geologic time scale are often changed and updated.
Mashutka [201]

Answer:

Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. ... The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

Explanation:

Hope this helps :)

The two strands in a DNA helix are described as being antiparallel, or in opposite orientations. If one DNA strand is in the 5'
s344n2d4d5 [400]

Answer: The answer is 3' - 5' direction

Explanation:

Since the template strand runs in 5' - 3' direction, antiparallel nature of the DNA double helix explains that the complimentary strand (non-template strand) runs in a 3' - 5' direction
