The t-test is a type of inference statistic used to determine if there is a significant difference between the means of two groups that may be related to a particular characteristic. The t-test is one of many tests used to test statistical hypotheses.

Inference statistics have two main purposes. Estimates for population groups (for example, the average SAT score for all 11th graders in the United States). Hypothesis testing to draw inferences about the population

One-way ANOVA is a common method for comparing three or more group means. The usual goal is to determine if the mean (or median) of at least one group is different from the other. Subsequent multiple comparison tests are often used to determine where differences occur.

irga5000 [103]

Answer:

The kind of error the researcher has done is a;

Type I error

Step-by-step explanation:

When carrying out hypothesis testing in statistical analysis, a type I error is the type of error said to have occurred when a null hypothesis that is true or correct is rejected which is a false positive conclusion

Given that that sugar box manufacturing company makes the boxes to be 100 g accurately, and that the researcher makes non-random or randomly selects packets which are not filled, the mean of the filled packets is expected to be 100 g making the conclusion for rejection of the null hypothesis a false positive rejection

43.12(bar on 12) in p/q form.​
arsen [322]

Answer:

1423/33

Step-by-step explanation:

Let x = 43.121212.........

Two digits are repeating after decimal point. So multiply both sides by 100

100x = 4312.1212       --------------(I)

   <u> x =      43.1212  </u>   -----------(II)   { subtract equation (II) form (I)}

99x =      4269

x= 4269/99   {reduce to simplest form by giving by 3rd table}

x = 1423/33
