Based on the z-statistic of –2.5 for the sample data, should the null hypothesis be rejected? Yes, because the z-statistic lies within the critical region. Yes, because the z-statistic lies outside of the critical region. No, because the z-statistic lies within the critical region. No, because the z-statistic lies outside of the critical region.

Answers

Answer:

No, because z-statistics lies within the critical region.

Step-by-step explanation:

The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.

Answer:

A) Yes, because the z-statistic lies within the critical region.

Step-by-step explanation:

Next one is B) The claim should be rejected.

Is 8/4 equivalent to 10/5?

Answers

These are just some equivalent fractions of 8/4:

2/1 = 4/2 = 6/3 = 8/4

= 10/5 = 12/6 = 14/7 = 16/8

= 18/9 = 20/10 = 22/11 = 24/12

= 26/13 = 28/14 = 30/15 = 32/16

= 34/17 = 36/18 = 38/19 = 40/20

= 42/21 = 44/22 = 46/23 = 48/24

= 50/25 = 52/26 = 54/27 = 56/28

= 58/29 = 60/30 = 62/31 = 64/32

= 66/33 = 68/34 = 70/35 = 72/36

= 74/37 = 76/38 = 78/39 = 80/40

= 82/41 = 84/42 = 86/43 = 88/44

= 90/45 = 92/46 = 94/47 = 96/48

= 98/49 = 100/50 = 102/51 = 104/52

= 106/53 = 108/54 = 110/55 = 112/56

= 114/57 = 116/58 = 118/59 = 120/60

= 122/61 = 124/62 = 126/63 = 128/64

= 130/65 = 132/66 = 134/67 = 136/68

= 138/69 = 140/70 = 142/71 = 144/72

= 146/73 = 148/74 = 150/75 = 152/76

= 154/77 = 156/78 = 158/79 = 160/80

= 162/81 = 164/82 = 166/83 = 168/84

= 170/85 = 172/86 = 174/87 = 176/88

= 178/89 = 180/90 = 182/91 = 184/92

= 186/93 = 188/94 = 190/95 = 192/96

= 194/97 = 196/98 = 198/99 = 200/100

So, yes.

Is (0,3) a solution to the equation y=x+3? yes
no

Is (1,-4) a solution to the equation y=-2x?
yes
no

Answers

1. To find out if (0,3) is a solution to y = x +3 you replace x and y with (0,3)

y = x + 3
3 = 0 + 3
3 = 3        Correct

The answer is YES


2. To find out if (1,-4) is a solution to y = -2x you replace x and y with (1,-4)

y = -2x
-4 = -2(1)
-4 = -2        Incorrect

The answer is NO
