alis dog weighs eight times as much as our cat together the two pets way 54 pounds how much does a Leah dog weigh

Svetllana [295]

Your wording is a little strange but If I am understanding this correctly, this one dog weighs 8 times more than the cats together. And the cats together are equal to 54 pounds. So
Dog- 8x
Cats Together- x- 54
8 (54)= 432 lb

g Suppose the investigators had made a rough guess of 0.14 for the value of the sample standard deviation, s, before collecting

Arada [10]

Answer:

The sample size is $n =326$

Step-by-step explanation:

From the question we are told that

The rough estimate of the standard deviation is $\sigma = 0.14$

The interval width is $w = 0.04$

Generally the margin of error is mathematically represented as

$E = \frac{w}{2}$

=> $E = \frac{0.04}{2}$

=> $E = 0.02$

From the question we are told the confidence level is 99% , hence the level of significance is

$\alpha = (100 - 99 ) \%$

=> $\alpha = 0.01$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 2.58$

Generally the sample size is mathematically represented as

$n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2$

=> $n = [\frac{ 2.58 * 0.14 }{0.02} ] ^2$

=> $n =326$
