A group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are list

Anit [1.1K]

Answer:

Step-by-step explanation:

Given that a group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below.

Data set is as ollows:

70 79 38 63 44 23 62 61 67 50 61 70 94 87 65

$Mean = 62.27Variance =333.35std dev = 18.258std error = 4.714$

H0: mu = 60 sec

Ha: mu not equals 60 sec

Mean diff = 2.27

$Mean = 62.27Variance =333.35std dev = 18.258std error = 4.714$

Test statistic = 2.27/SE =0.4815

p value =0.6376

Since p>0.05, we accept null hypothesis

i.e. there is statistical evidence to say that students are reasonably good at estimating one minute

Find the slope of the line described by 3y = x + 6.

Alexxx [7]

$3y = x +6 \\\\\implies y = \dfrac 13 (x+6)\\\\\implies y = \dfrac 13 x + 2\\\\\text{The above equation is in a form of y = mx +b, where m is the slope.}\\\\\\\text{Hence slope of the line,}~ m= \dfrac 13$

Travka [436]

Answer:

<h2>m = 6.43 (approx. )</h2>

Step-by-step explanation:

49 - 3m = 4m + 4

=> 49 - 4 = 4m + 3m

=> 45 = 7m

$= > \frac{45}{7} = m$

=> 6.428571... = m

=> m = 6.43 (approx. ) (Ans)
