Answer:

Intervals = (1,064) , (1,036)

Step-by-step explanation:

Given:

Use 95% method

Mean = 1,050

Standard deviation = 7

Find:

Intervals.

Computation:

95% method.

⇒ Intervals = Mean ± 2(Standard deviation)

⇒ Intervals = 1,050 ± 2(7)

⇒Intervals = 1,050 ± 14

⇒ Intervals = (1,050 + 14) , (1,050 - 14)

⇒ Intervals = (1,064) , (1,036)

SSSSS [86.1K]
130, is the answer.. so here's me having to come back and to explain,because this questions is SO hard.

WOW, fascinating.
Thanks Brainly's "monitors" such help. -_-

Assume that the weights of spawning Chinook salmon in the Columbia river are normally distributed. You randomly catch and weigh
s344n2d4d5 [400]

Answer: The point estimate for the mean weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample (\overline{x}) = 31.2 pounds .

Step-by-step explanation:

The weights of spawning Chinook salmon in the Columbia river are normally distributed.

Given :  The mean weight from your sample is 31.2 pounds with a standard deviation of 4.4 pounds.

The point estimate for the mean (\mu) weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample (\overline{x}) i.e. is 31.2 pounds because the best point estimate for population mean is the sample mean. [in normal distribution]
