Answer:

Step-by-step explanation:

since the data is already arranged in ascending to descending u don't have to change.

upper quartile (Q3) = 3(n + 1)/4 (n means no of data)

=3(10 + 1)/4

=3*11/4

=33/4

=8.25

=8 th term + 0.25(9 th term - 8 th term)

=11 + 0.25(13 - 11)

=11 + 0.25*2

=11 + 0.5

=11.5

given that a test statistic in a left tailed test is z equals -1.25, use a 0.05 significance level to find the p-value and state

mr Goodwill [35]

Answer:

The p-value of the test is 0.106.

The null hypothesis will be accepted at 5% level of significance.

Step-by-step explanation:

The hypothesis test is left-tailed.

The test statistic value is: z = -1.25.

The significance level of the test is: α = 0.05.

The p-value of a left-tailed hypothesis test is:

$p-value=P(Z$

The p-value of the test is 0.106.

**Use the z-table for the probability.

Decision rule:

If the p-value is less than the significance level the null hypothesis will be rejected and if it is more than the significance level the null hypothesis will be accepted.

The p-value = 0.106 > α = 0.05.

The null hypothesis will be accepted at 5% level of significance.

The courtyard behind Jennie's house is shaped like a trapezoid. The bases measure 8 meters and 11 meters. The height of the trap

Mkey [24]

Area of the trapezoid=
1/2(b1+b2)×2

A=1/2(8+11)×12
A=1/2(19)×12
A=6×19
A=114 square meters. As a result, the area of the courtyard is 114 square meters. Hope it help!

The equation to model Exponential Growth is: y=a(1+r)t y= total amount a= starting amount r= the growth rate as a decimal t= num

vlada-n [284]

The equation that can be used to determine the number of cells after x hours is; y = 0.5x + 30.

<h3>Linear model Equations</h3>

It follows from the task content that;

The scientist starts with a sample of 30 bacteria cells, it follows that the intercept of the linear model is 30.

Additionally, since the number of bacteria cells increases by 50% every hour implies that the rate of change, slope of the equation is 0.5.

Hence, the required equation is; y = 0.5x + 30.
