A number of robbers were discussing how best to share some stolen rolls of

kupik [55]

Answer:

83

Step-by-step explanation:

Let the number of robbers be x

If they share 6 rolls each, the tota rolls will be 6x and since they have five remainder, the overall total is then 6x+5

In case they share 7 rolls each, it means they have 7x rolls but here they will be less 8 rolls hence 7x-8 is the overall total.

Equating these two

7x-8=6x+5

Arranging similar terms

7x-6x=8+5

x=13

Therefore, the robbers are 13

The rolla they have will be

6(13)+5=83

Or

7(13)-8=83

Answer:

The test statistic is $t = 3.744$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 140$

The The level of significance is $\alpha = 0.05$

The sample size is n = 18

The null hypothesis is $H_o : \mu = 140$

The alternative hypothesis is $H_a : \mu > 140$

The sample mean is $\= x = 155$

The standard deviation is $\sigma = 17$

Generally the test statistics is mathematically represented as

$t = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

substituting values

$t = \frac{ 155 - 140 }{ \frac{ 17 }{ \sqrt{18} } }$

$t = 3.744$
