Using the 5%level of significance,is there sufficient evidence to conclude that the new strategy increased spending?

a.No,because the p-value(0.055)is above the significance level(0.05)we fail reject the null hypothesis and conclude the new strategywas unable to increase spending.

b.No,since the p-value(0.024)is lower than the significance level(0.05),we fail toreject the null hypothesis and conclude there is no evidence of an increase in spending.

c.Yes,because the p-value (0.055)is above the significance level (0.05)we reject the null hypothesis and conclude the new strategy increased spending.
