The table and graph both represent the same relationship.

Llana [10]

Answer:

x = 1

Step-by-step explanation:

From the table shown in the picture,

For input value x = 1, output values of y = 2, 4, 6, 8, 10

Similarly, from the graph shown,

For input value x = 1, output values of y = 2, 4, 6, 8, 10

Therefore, both will represent the same relationship.

From the graph attached, straight line parallel to y-axis is x = 1.

Therefore, x = 1 will be the correct option.

A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for t

hoa [83]

Answer:

Since p value <0.1 accept the claim that oven I repair costs are more

Step-by-step explanation:

The data given for two types of ovens are summarised below:

Group Group One Group Two

Mean 85.7900 78.6700

SD 15.1300 17.8400

SEM 1.9533 2.3840

N 60 56

Alpha = 10%

$H_0: \mu_1 - \mu_2 =0\\H_a: \mu_1 - \mu_2> 0$

(Right tailed test)

The mean of Group One minus Group Two equals 7.1200

df = 114

standard error of difference = 3.065

t = 2.3234

p value = 0.0219

If p value <0.10 reject null hypothesis

4) Since p value <0.1 accept the claim that oven I repair costs are more
