    See ecplanation below

    Step-by-step explanation:

    False.

    On the Data analysis tool from excel we can conduct the following procedures:

    Anova: Single Factor

    Anova: Two factor with replication

    Anova: Two factor without replication

    Correlation

    Covariance

    Descriptive statistics

    Exponential smoothing

    F-test Two sample for Variances

    Fourier analysis

    Histogram

    Moving Average

    Random number generation

    Rank and percentile

    Regression

    Sampling

    t test: Paired two sample for means

    t tes: Two sample assuming equal variances

    t test: Two sample Assuming Unequal Variances

    z test: Two sample for means

    And as we can see we don't have an specific procedure just to obtain confidence interval for the difference of proportions. We need to remember that if we select a z test in excel, for example the output will contain the confidence associated to the parameter, but for this case is not too easy obtain a confidence interval for the difference of proportion like on a statistical software as (Minitab, R, SAS, etc) since all of these statistical softwares are elaborated in order to conduct all the possible statistical tests and confidence intervals for parameters of interest.
