A scale was constructed by taking per respondent calculating the mean score on these 8 items.

    The data from our sample showed that the level of satisfaction with the current job of workers with a permanent contract was significantly different from workers with temporary contracts. The calculation of * In effect shows that the difference between the mean scores of the two groups differs significantly from * [—Getal–]**.

    2. FALSE: Text: the 5% significance level. Getal: 0.05.
    3. FALSE: Text: the 5% significance level. Getal: 0.
    4. FALSE: Text: a 95% confidence interval. Getal: 0.05.
