Answer:

slope is 3

Step-by-step explanation:

Slope = $\frac{change in y }{change in x }$

change in y = (13-7), (19-13), (25-19), (31-25)

change in y = 6

Change in x = (4-2), (6-4), (8-6), (10-8)

Change in x = 2

Therefore slope = $\frac{6}{2}$

Slope = 3

The owner of a fish market has an assistant who has determined that the weights of catfish are normally distributed, with mean

LiRa [457]

Answer:

$P(X\geq 3.4)=0.0228$

Step-by-step explanation:

Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.

-We calculate the probability of a mean of 3.4 as follows:

#First determine the z-value:

$z=\frac{\bar X -\mu}{\sigma/\sqrt{n}}\\\\=\frac{3.4-3.2}{0.8/\sqrt{64}}\\\\=2.000$

#We then determine the corresponding probability on the z tables:

$Z(X\geq 3.4)=1-P(X$

Hence, the probability of obtaining a sample mean this large or larger is 0.0228
