In tilapia, an important freshwater food fish from Africa, the males actively court females. They have more incentive to court a female who has already laid all of her eggs, but can they tell the difference? an experiment was done to measure the male tilapia's response to the smell of female fish. Water containing feces from females that were either pre-ovulatory (they still had eggs) or post-ovulatory (they had already laid their eggs) was washed over the gills of males hooked up to an electro-olfactogram machine which measured when the senses of the males were excited. The amplitude of the electro-olfactogram was used as a measure of the excitability of the males in the two different circumstances. Six males were exposed to the scent of pre-ovulatory females; their readings average 1.51 with a standard deviation of .25. Six different males were exposed to post-ovulatory females; their average readings of 0.87 with standard deviation is .31. Assume that the electro-olfactogram readings were approximately normally distributed within the groups.(A) test for a difference in the excitability of the males with exposure to these two types of females(B) what is the estimated average difference in electro-olfactogram readings between the two groups? What is the 95% confidnece limit for the difference between population means?
At the end of the day of teaching the skill of cutting and sewing to make capes, Ms. Ironperson and Mr. Thoro decided to go to the Shawarma Mediterranean Grill.

The sum of a number and 2 times its reciprocal is -3

Answers

Answer:

(-2,-1)

Step-by-step explanation:

let the number=x

its reciprocal=1/x

x+2(1/x)=-3

x+2/x=-3

x²+2=-3x

x²+3x+2=0

(x+2)(x+1)=0

x=-2,-1

A company manufacturing computer chips finds that 8% of all chips manufactured are defective. In an effort to decrease the percentage of defective chips, management decides to provide additional training to those employees hired within the last year. After training was implemented, a sample of 450 chips revealed only 27 defects. A hypothesis test is performed to determine if the additional training was effective in lowering the defect rate. Which of the following statement is true about this hypothesis test?a) The additional training significantly increased the defect rate.b) The additional training significantly lowered the defect rate.c) The additional training did affect the defect rate.d) The additional training did not significantly lower the defect rate.e) None of these.

Answers

Answer:

d) The additional training did not significantly lower the defect rate

Step-by-step explanation:

Let proportion of defective chips be = x

Null Hypothesis [H0] : Additional training has no impact on defect rate x = 8% = 0.08

Alternate Hypothesis [H1] : Additional training has impact on defect rate x < 8% , x < 0.08

Observed x proportion (mean) : x' = 27 / 450 = 0.06

z statistic = [ x' - x ] / √ [ { x ( 1-x ) } / n ]

( 0.06 - 0.08 ) / √ [ 0.08 (0.92) / 450 ]

= -0.02 / √ 0.0001635

= -0.02 / 0.01278

z = - 1.56

Since calculated value of z, 1.56 < tabulated value of z at assumed 0.01 significance level, 2.33

Null Hypothesis is accepted, 'training didn't have defect rate reduction impact' is concluded

How do you answer 8 - 1 1/6=

Answers

1 $(1)/(6)$ is the same as 1.16666667.

8 - 1.167 = 6.833.

first you'd have to make 8 a fraction so it would be 8/1 then you need a common denominator so you multiply 8 and 1 by 6

8 times 6 = 48
1 times 6 = 6

then you subtract 11 from 48 = the answer is 37/6

48-11= 37 so then it is 37/6 do not simplify if it says not to but if you were to simplify you would divide 37 by 6 and get 6 with 1 remaining so the answer would be 6 1/6

I hope this helps!

PLEASE HELP!Which is the correct classification of square root of 18?

A. irrational number, non-repeating decimal
B. irrational number, terminating decimal
C. rational number, terminating decimal
D .rational number, non-repeating decimal

Answers

The correct classification of the square root of 18 is: A. irrational number, non-repeating decimal.

To determine the classification of the square root of 18, let's break down the steps:

1. Calculate the square root of 18:

$√(18) \approx 4.24264068712$

2. Rational or Irrational?

The square root of 18 is an irrational number because it cannot be expressed as a fraction of two integers, and it is non-terminating, non-repeating decimal.

Rational numbers can be expressed as fractions, and their decimal representation either terminates (e.g., 1/4 = 0.25) or repeats in a pattern (e.g., 1/3 = 0.333...).

Since $√(18)$ cannot be expressed as a simple fraction, and its decimal representation continues infinitely without repeating, it is classified as an irrational number, non-repeating decimal.

So, the correct classification is: A. irrational number, non-repeating decimal.
